Question 1Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

Under the Indian Constitution, which authority formally declares war or concludes peace on behalf of the nation?

  1. The President acting on the advice of the Council of Ministers Correct answer.
  2. The Chief of Defence Staff after consulting the three service chiefs
  3. The Parliament by a two-thirds majority resolution
  4. The Union Cabinet's Security Committee independently of the President

Explanation

The Constitution vests the supreme command of the Defence Forces in the President, and war and peace are declared or concluded in the President's name on the advice of the Council of Ministers. Parliament's role is legislative and budgetary rather than declaratory of war.

Question 2Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

Which Article of the Indian Constitution states that the supreme command of the Defence Forces of the Union is vested in the President?

  1. Article 72
  2. Article 53 Correct answer.
  3. Article 149
  4. Article 51

Explanation

Article 53 vests the executive power of the Union, including the supreme command of the Defence Forces, in the President, exercisable directly or through subordinate officers. The other Articles cited deal with international peace, pardons and audit respectively.

Question 3Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

In the Indian defence structure, the term 'tri-service command' refers to a command in which:

  1. Each service rotates command annually among its chiefs
  2. Only reserve and territorial units are combined
  3. One service controls the other two services' budgets
  4. All three services operate under a single theatre commander Correct answer.

Explanation

A tri-service (joint) command places elements of the Army, Navy and Air Force under one unified commander for a defined theatre or function. The Andaman and Nicobar Command is the established Indian example of this arrangement.

Question 4Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

The Andaman and Nicobar Command is significant in Indian defence organisation because it is:

  1. The only tri-service theatre command of the Indian armed forces Correct answer.
  2. A training establishment for foreign cadets
  3. A purely civilian coastal administration body
  4. The oldest single-service command of the Indian Army

Explanation

The Andaman and Nicobar Command, raised in 2001, is India's first and only operational unified theatre command integrating Army, Navy and Air Force assets. It guards the approaches to the Malacca Strait and the Bay of Bengal.

Question 5Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

Which body is the highest decision-making organ of the Ministry of Defence for matters of defence policy and coordination among the three services?

  1. The Defence Acquisition Council
  2. The Chiefs of Staff Committee Correct answer.
  3. The National Security Advisory Board
  4. The Defence Research and Development Board

Explanation

The Chiefs of Staff Committee, comprising the three service chiefs, is the senior military body for inter-service coordination and military advice to the government. It is chaired by the senior-most chief, with the CDS role evolving to strengthen jointness.

Question 6Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

In Indian military terminology, 'theatreisation' primarily means:

  1. Shifting defence production to the private sector
  2. Creating integrated geographic commands for joint operations Correct answer.
  3. Deploying forces only for ceremonial parades
  4. Reducing the armed forces to a single uniform service

Explanation

Theatreisation is the reorganisation of forces into integrated geographic or functional commands where all services operate jointly under one commander. It aims at unity of effort, faster decision-making and efficient use of resources.

Question 7Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

The principal aim of a nation's defence policy is best described as:

  1. Ensuring the military controls the national budget
  2. Eliminating the need for diplomacy in foreign affairs
  3. Maximising the size of the standing army in peacetime
  4. Protecting national sovereignty, territorial integrity and vital interests Correct answer.

Explanation

Defence policy exists to safeguard sovereignty, territorial integrity and core national interests, using military means in support of national security objectives. It is subordinate to national policy and works alongside diplomacy rather than replacing it.

Question 8Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

Which of the following is the clearest example of a 'non-kinetic' element of national defence?

  1. An amphibious landing on a hostile coast
  2. Artillery bombardment of a forward post
  3. Strategic communication to counter hostile propaganda Correct answer.
  4. An armoured brigade advancing across a border

Explanation

Non-kinetic instruments influence an adversary's will and perceptions without direct physical destruction, and information operations such as strategic communication are typical examples. The other options all involve direct application of lethal force.

Question 9Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

'Deterrence' in defence studies is achieved when:

  1. Forces are withdrawn from all disputed frontiers
  2. A country maintains the largest possible army in peacetime
  3. An adversary is convinced that the cost of aggression will outweigh any gain Correct answer.
  4. Defence spending is reduced below the level of neighbours

Explanation

Deterrence works through the adversary's calculation that the expected punishment or denial of success exceeds any benefit from attack. Capability, credibility and communication of the threat are all essential to it.

Question 10Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

In Indian defence vocabulary, 'strategic autonomy' most nearly means:

  1. Refusing all military imports permanently
  2. The ability to take independent decisions on national security without external pressure Correct answer.
  3. Outsourcing intelligence assessment to allies
  4. Allowing foreign powers to station troops on Indian soil

Explanation

Strategic autonomy refers to the capacity to make sovereign decisions on security and foreign policy according to national interest, even while cooperating with partners. It does not mean isolation or a total ban on imports.

Question 11Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

Which of the following is a stated role of the Indian armed forces in internal security?

  1. Collecting income tax from citizens
  2. Aiding civil authorities during natural disasters and disturbances Correct answer.
  3. Conducting elections in states
  4. Framing the annual Union Budget

Explanation

The armed forces provide aid to civil authority during calamities, insurgencies and law-and-order crises when requested by the state administration. They act in support of civil power, which retains primacy.

Question 12Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

When the armed forces are requisitioned to assist civil authorities in a state, the legal position is that:

  1. Civil authority retains overall responsibility while the military acts in support Correct answer.
  2. The senior-most military officer becomes the district magistrate
  3. The state legislature must be dissolved
  4. Military law replaces civil law in the affected area

Explanation

Aid to civil authority is provided on request, with the civil administration remaining responsible for the situation and the military assisting within defined limits. This preserves the constitutional principle of civilian supremacy.

Question 13Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

The term 'proxy war', as used in Indian security discourse, refers to:

  1. A war authorised by the United Nations
  2. Hostile activity sponsored by a state through non-state actors Correct answer.
  3. A war fought entirely at sea
  4. A conflict confined to cyber space

Explanation

A proxy war involves a state using non-state groups or other surrogates to inflict damage on an adversary while limiting its own direct involvement. India has long faced cross-border terrorism described in these terms.

Question 14Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

A 'Low Intensity Conflict' in Indian military usage is best characterised by:

  1. Full-scale conventional war between two states
  2. Nuclear exchange between adversaries
  3. Protracted operations below the threshold of general war, often against irregular forces Correct answer.
  4. A single decisive armoured battle

Explanation

Low Intensity Conflict covers counter-insurgency, counter-terrorism and border-management operations that are prolonged but remain below conventional war. It demands restraint, intelligence and population-oriented tactics rather than massed firepower.

Question 15Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

The primary purpose of the Indian Navy's maritime security role in the Indian Ocean Region is to:

  1. Protect sea lines of communication and maritime interests Correct answer.
  2. Control global shipping tariffs
  3. Manage port customs revenue
  4. Regulate fishing licences for foreign vessels

Explanation

Sea lines of communication carry most of India's trade, including energy imports, so the Navy's maritime role centres on keeping them secure and protecting exclusive economic zone interests. Commercial regulation and revenue functions belong to civil agencies.

Question 16Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

Under the United Nations Convention on the Law of the Sea, a coastal state's Exclusive Economic Zone extends up to:

  1. 24 nautical miles from the baseline
  2. 200 nautical miles from the baseline Correct answer.
  3. 12 nautical miles from the baseline
  4. 350 nautical miles from the baseline in all cases

Explanation

UNCLOS grants coastal states sovereign rights over resources within an EEZ extending 200 nautical miles from the baseline. The territorial sea is 12 nautical miles and the contiguous zone 24 nautical miles.

Question 17Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

India's Maritime Anti-Piracy Act, 2022 is chiefly significant because it:

  1. Transferred maritime security to state governments
  2. Banned Indian ships from the Gulf of Aden
  3. Provides a legal framework for Indian forces to counter piracy at sea Correct answer.
  4. Abolished the Indian Navy's overseas deployments

Explanation

The Act gives statutory backing for the suppression of piracy, including apprehension and prosecution of pirates, supporting Indian naval anti-piracy operations. It strengthens legal authority rather than restricting deployments.

Question 18Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

In air power doctrine, 'air superiority' means:

  1. The ability to fly only at night
  2. Ownership of the largest number of transport aircraft
  3. The complete absence of any enemy aircraft in the world
  4. A state in which an air force can conduct operations without prohibitive interference by the enemy Correct answer.

Explanation

Air superiority is a relative condition in which friendly air operations can proceed without effective interference from the adversary's air and air-defence forces. It is a degree of control, not the total elimination of enemy aviation.

Question 19Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

Which of the following best describes the role of unmanned aerial vehicles in modern military operations?

  1. They operate exclusively in outer space
  2. They are used only for ceremonial flypasts
  3. They provide surveillance, reconnaissance and precision-strike options while reducing risk to pilots Correct answer.
  4. They replace all manned combat aircraft permanently

Explanation

UAVs are valued for persistent surveillance, target acquisition and increasingly for strike missions, all without exposing aircrew to immediate danger. They complement rather than wholly replace manned systems.

Question 20Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

The concept of 'no first use' in India's nuclear doctrine means that India:

  1. Has delegated launch authority to the United Nations
  2. Will never build nuclear weapons
  3. Will use nuclear weapons only in retaliation against a nuclear attack on Indian forces or territory Correct answer.
  4. Will use nuclear weapons against any conventional attack

Explanation

India's declared doctrine commits to no first use, with nuclear retaliation reserved for a nuclear attack on Indian forces or territory, while maintaining a credible minimum deterrent. It does not preclude possession or a response.

Question 21Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

The Nuclear Command Authority of India is chaired by:

  1. The Chief of the Air Staff
  2. The National Security Adviser
  3. The Chairman of the Atomic Energy Commission
  4. The Prime Minister Correct answer.

Explanation

The Nuclear Command Authority is chaired by the Prime Minister and is the sole body that can authorise the use of nuclear weapons. It has a Political Council and an Executive Council to advise and execute decisions.

Question 22Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

'Credible minimum deterrence' in India's nuclear posture implies that India:

  1. Rejects the possession of any delivery systems
  2. Seeks numerical equality with every nuclear-armed state
  3. Maintains a stockpile sufficient to survive a first strike and retaliate, without pursuing parity with major powers Correct answer.
  4. Relies entirely on allies for its nuclear umbrella

Explanation

Credible minimum deterrence requires a survivable force able to inflict unacceptable retaliation, sized to the minimum judged sufficient rather than to parity. Survivability is achieved through measures such as dispersal and the sea-based leg.

Question 23Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

Which organisation is responsible for India's defence research and the development of military technology?

  1. Defence Research and Development Organisation Correct answer.
  2. Bhabha Atomic Research Centre
  3. Council of Scientific and Industrial Research
  4. Indian Space Research Organisation

Explanation

DRDO, under the Ministry of Defence, carries out research and development of defence systems, from missiles to electronics, for the armed forces. The other bodies serve space, general scientific and atomic energy purposes.

Question 24Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

The 'Make in India' thrust in defence procurement is intended primarily to:

  1. Transfer procurement decisions to the states
  2. Eliminate all foreign collaboration in defence
  3. Increase imports of complete weapon systems
  4. Build domestic design and manufacturing capability while reducing import dependence Correct answer.

Explanation

The policy encourages indigenous design, development and manufacture, including through partnerships and technology transfer, to reduce dependence on imports. It permits foreign collaboration where it builds domestic capability.

Question 25Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

A defence offset obligation in an arms contract normally requires the foreign supplier to:

  1. Reduce the price below cost
  2. Provide free training to the seller's own forces
  3. Pay a penalty for late delivery only
  4. Reinvest a specified portion of the contract value in the buyer's domestic economy Correct answer.

Explanation

Offset clauses require the foreign vendor to reinvest a defined share of contract value through local production, technology transfer or exports, thereby generating domestic industrial benefit. They are not simply penalties or discounts.

Question 26Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

In Indian defence planning, the term 'jointness' refers to:

  1. The merging of the Army and the Air Force into a single uniformed service
  2. The integration and coordinated employment of two or more services under a unified command Correct answer.
  3. The practice of recruiting soldiers from more than one state of India
  4. The sharing of defence equipment between India and a foreign ally

Explanation

Jointness in military doctrine means that different services plan and operate together under a single commander rather than in separate silos. It is about coordinated employment and shared command structures, not about abolishing separate services. India's move toward Integrated Theatre Commands is an example of pursuing jointness.

Question 27Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

The Chief of Defence Staff (CDS) in India is best described as:

  1. The senior-most uniformed officer who advises the government on military matters and promotes tri-service integration Correct answer.
  2. The head of the Defence Research and Development Organisation
  3. The civilian Defence Secretary who controls the defence budget
  4. The commander of a single service, such as the Army Chief

Explanation

The CDS is the principal military adviser to the government and is mandated to foster jointness among the three services. The post is a uniformed appointment, distinct from the civilian bureaucracy. The CDS also heads the Department of Military Affairs.

Question 28Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

Which body in India is the apex institution for formulating defence policy and coordinating the armed forces with the Ministry of Defence?

  1. The Ministry of External Affairs
  2. The Defence Acquisition Council
  3. The National Security Council Correct answer.
  4. The Reserve Bank of India

Explanation

The National Security Council, chaired by the Prime Minister, is the apex body for national security and defence policy advice. It sits above individual ministries in coordinating strategic matters. The Defence Acquisition Council deals specifically with procurement approvals.

Question 29Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

In Indian military usage, 'mobilisation' refers to:

  1. The process of assembling and preparing forces for active military operations Correct answer.
  2. The negotiation of a ceasefire with an adversary
  3. The retirement of senior officers from service
  4. The construction of permanent peacetime barracks

Explanation

Mobilisation is the act of organising and moving forces, reserves and logistics into a state ready for war or operations. It is a preparatory and deployment process, not a peacetime construction or diplomatic activity. The speed of mobilisation is a key strategic factor.

Question 30Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

The primary function of a country's air defence system is to:

  1. Train pilots for commercial airlines
  2. Provide transport aircraft for civilian disaster relief only
  3. Detect, identify and intercept hostile aircraft or missiles approaching its airspace Correct answer.
  4. Manufacture aircraft engines for export

Explanation

Air defence is organised to detect, identify and neutralise aerial threats before they can strike defended assets. It combines radar surveillance, command and control, and interceptors such as fighters or surface-to-air missiles. Civil relief and exports are not its primary purpose.

Question 31Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

In defence studies, 'logistics' primarily deals with:

  1. The movement and supply of personnel, equipment and material to sustain military operations Correct answer.
  2. The drafting of treaties between nations
  3. The design of military uniforms and insignia
  4. The legal prosecution of prisoners of war

Explanation

Logistics covers the planning and execution of movement, supply, maintenance and evacuation needed to sustain forces. It is often described as the backbone of military operations because combat power depends on sustained supply. Uniform design, legal prosecution and treaty drafting are separate fields.

Question 32Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

The term 'insurgency' in Indian internal security vocabulary is best understood as:

  1. A formal declaration of war between two states
  2. A trade dispute between two neighbouring countries
  3. A peaceful protest march by a political party
  4. An organised armed movement that seeks to overthrow or challenge established authority through irregular means Correct answer.

Explanation

Insurgency involves organised, often irregular, armed action aimed at challenging or overthrowing state authority. It differs from lawful protest and from inter-state war. Indian security discourse treats insurgency as an internal security challenge requiring a calibrated response.

Question 33Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

Which of the following is the best example of 'interoperability' in defence?

  1. A factory producing rifles for the army
  2. Two allied air forces using common communication protocols and refuelling systems so their aircraft can operate together Correct answer.
  3. A country increasing its defence budget by ten per cent
  4. A soldier receiving a bravery medal

Explanation

Interoperability is the ability of different forces or systems to work together, often through shared standards, communications and equipment. Common protocols and refuelling systems are a direct example. Budget increases, medals and factory production do not by themselves create the ability to operate jointly.

Question 34Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

A country decides to reduce its dependence on imported defence equipment by building domestic production capacity. Which strategic objective does this most directly serve?

  1. Reducing its diplomatic engagement with other countries
  2. Lowering the training standards of its armed forces
  3. Enhancing self-reliance in defence and reducing vulnerability to supply disruptions Correct answer.
  4. Increasing the number of foreign suppliers in its inventory

Explanation

Domestic production capacity reduces dependence on foreign suppliers and the risk of supply cut-offs during crises. This is the logic behind self-reliance drives such as indigenous defence manufacturing. It does not imply lowering training standards or withdrawing from diplomacy.

Question 35Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

A coastal state wants to protect its offshore oil installations from sea-borne attack. Which combination of measures best addresses this threat?

  1. Withdrawing the coast guard from the region
  2. Maritime surveillance, naval patrols and physical security around the platforms Correct answer.
  3. Reducing the number of naval ships in the area
  4. Relying solely on diplomatic protests to deter attackers

Explanation

Protecting offshore installations requires layered defence: surveillance to detect threats, patrols to intercept them, and physical security to harden the platforms. Reducing naval presence or withdrawing the coast guard weakens protection. Diplomacy alone cannot stop an imminent attack.

Question 36Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

In a counter-insurgency campaign, the principle of 'minimum force' implies that:

  1. The state should hand over operations entirely to civilian police
  2. The state should use only the degree of force necessary to achieve the objective while limiting civilian harm Correct answer.
  3. The state should avoid using any force at all
  4. The state should always use its maximum available firepower

Explanation

Minimum force means calibrating the use of force to what is necessary to achieve the military aim, so as to avoid alienating the population. In counter-insurgency, excessive force can strengthen the insurgent cause. It does not mean using no force or abdicating military responsibility.

Question 37Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

Why is 'command and control' considered critical in modern military operations?

  1. It ensures that forces and weapons are directed coherently and that authority for action is clearly defined Correct answer.
  2. It removes the need for logistics
  3. It guarantees that no equipment will ever fail
  4. It eliminates the requirement for training

Explanation

Command and control provides the authority, decision-making and communication structure that directs forces coherently. Without it, even well-equipped forces cannot act in a coordinated way. It does not remove the need for logistics or training, nor can it prevent equipment failure.

Question 38Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

A nation adopts a policy of maintaining a small but survivable nuclear force able to retaliate after a first strike. This posture is best described as:

  1. Assured retaliation Correct answer.
  2. Pre-emptive first strike
  3. Disarmament
  4. Nuclear proliferation

Explanation

Assured retaliation is the ability to survive a first strike and inflict unacceptable damage in return, which underpins deterrence. A pre-emptive first strike is the opposite posture. Proliferation and disarmament describe the spread or reduction of weapons, not this retaliatory posture.

Question 39Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

Which of the following best explains why terrain matters in defensive military planning?

  1. Terrain determines the rank structure of an army
  2. Natural features such as rivers and mountains can channel or slow an attacker's movement and favour the defender Correct answer.
  3. Terrain has no effect on the movement of military forces
  4. Terrain only matters for naval operations

Explanation

Terrain shapes mobility, observation and fields of fire, so defenders use natural features to slow or channel attackers. Mountains and rivers are classic examples of terrain that favours a defender. Terrain does not set rank structures and is not limited to naval operations.

Question 40Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

In Indian defence procurement, 'emergency procurement' procedures are intended to:

  1. Allow the armed forces to purchase equipment without any specification
  2. Replace long-term indigenous development entirely
  3. Enable rapid acquisition of critical equipment when urgent operational needs arise Correct answer.
  4. Bypass parliamentary oversight of the defence budget permanently

Explanation

Emergency procurement powers exist to meet urgent operational requirements quickly, while still following defined procedures. They do not remove oversight or specifications, nor do they replace long-term development. The purpose is speed within a controlled framework.

Question 41Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

The concept of 'strategic depth' in military planning refers to:

  1. The number of officers in a headquarters
  2. The depth of a naval harbour
  3. The space and resources available behind the front line to absorb an attack and sustain defence Correct answer.
  4. The distance between two allied capitals

Explanation

Strategic depth is the geographic and resource buffer behind the forward line that allows a defender to absorb an attack, regroup and sustain operations. It is a broad strategic concept, not a physical measurement of harbours or headquarters. Depth reduces the risk of rapid collapse.

Question 42Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

Which of the following best illustrates the principle of 'economy of effort' in military operations?

  1. Deploying every available unit to every sector at once
  2. Spending the entire defence budget on a single weapon system
  3. Reducing the number of soldiers to save money
  4. Allocating the minimum necessary force to secondary tasks so that maximum strength can be concentrated on the main objective Correct answer.

Explanation

Economy of effort means husbanding resources by using only what is needed on secondary tasks and concentrating strength where it matters. It is a principle of war aimed at efficiency and concentration. It does not mean spreading all units everywhere or simply cutting personnel.

Question 43Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

A government wants to strengthen civil-military relations in a democracy. Which measure is most consistent with democratic civil-military norms?

  1. Allowing the military to set its own budget without civilian review
  2. Removing parliamentary oversight of defence spending
  3. Ensuring that the armed forces remain subordinate to elected civilian authority Correct answer.
  4. Permitting the military to conduct foreign policy independently

Explanation

Democratic civil-military relations rest on the supremacy of elected civilian authority over the armed forces. Civilian review of budgets and policy keeps the military accountable. Independent military budgeting or foreign policy would undermine that principle.

Question 44Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

Which of the following best describes the role of a coast guard, as distinct from a navy?

  1. Formulating the country's nuclear doctrine
  2. Enforcing maritime law and safety in peacetime within national waters Correct answer.
  3. Conducting offensive combat operations far from home waters
  4. Managing the national army's recruitment

Explanation

Coast guards are primarily law-enforcement and safety agencies operating in national waters in peacetime, handling tasks such as search and rescue, policing and fisheries protection. Navies are organised for military combat roles. Nuclear doctrine and army recruitment belong to other bodies.

Question 45Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

In the context of defence economics, 'defence offset' is best understood as:

  1. The pension paid to retired soldiers
  2. The tax paid by defence companies to the government
  3. A reduction in the price of weapons due to inflation
  4. A contractual obligation on a foreign supplier to reinvest or source part of the contract value within the buyer's country Correct answer.

Explanation

A defence offset requires the foreign supplier to reinvest in, or source from, the buyer's economy as part of a defence contract. It is intended to build domestic industrial capability and recover part of the contract value. It is not a price adjustment, a tax, or a pension.

Question 46Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

A country's defence forces are deployed to assist civil authorities after a major earthquake. Which principle should guide this deployment?

  1. Military takeover of all relief distribution and administration
  2. Humanitarian assistance under civil control, with the military supporting rather than supplanting civil authority Correct answer.
  3. Use of the deployment to test new weapons on civilians
  4. Refusal to coordinate with civilian agencies

Explanation

Disaster relief is a humanitarian task in which the military supports civil authorities, who remain in charge. Coordination with civilian agencies is essential for effective relief. The military does not take over civil administration, nor should relief be used for weapons testing.

Question 47Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

Which of the following best explains the strategic significance of 'choke points' in maritime security?

  1. Ports used only for fishing
  2. Narrow sea passages that concentrate shipping and can be controlled or disrupted, affecting trade and naval movement Correct answer.
  3. Rivers used for inland irrigation
  4. Wide open oceans where ships rarely travel

Explanation

Choke points are narrow maritime passages through which a large volume of trade and naval traffic must pass, so controlling or disrupting them has strategic consequences. Their importance lies in concentration and vulnerability. Open oceans, fishing ports and irrigation rivers do not fit this definition.

Question 48Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

A defence planner argues that 'deterrence by denial' differs from 'deterrence by punishment'. Which statement correctly captures the distinction?

  1. Denial applies only to nuclear weapons, while punishment applies only to conventional forces
  2. Denial relies on retaliation, while punishment relies on defence
  3. Denial seeks to convince an adversary that an attack will fail; punishment threatens severe retaliation if it occurs Correct answer.
  4. Both terms mean the same thing in all doctrines

Explanation

Deterrence by denial aims to make the adversary's attack fail by defensive measures, while deterrence by punishment threatens costly retaliation. The two approaches rely on different mechanisms, defence versus retaliation. They are distinct concepts and are not tied exclusively to one type of weapon.

Question 49Defence Studies (PSEB Senior Secondary elective) - official content domains and weights not published in the source; provisional equal split pending verification

In the study of national power, 'soft power' in a defence context is best illustrated by:

  1. Imposing a naval blockade on a rival
  2. Deploying armoured divisions across a border
  3. Attracting partners through defence diplomacy, training exchanges and reputation rather than coercion Correct answer.
  4. Increasing the number of ballistic missiles in service

Explanation

Soft power works through attraction and persuasion, such as defence diplomacy, joint exercises and training exchanges that build influence without coercion.
