Which one of the following pairs is not correctly matched?
(Indian Army Corps: Headquarters)
- A3 Corps : Dimapur
- B4 Corps : Tezpur
- C14 Corps : Leh
- D33 Corps : SrinagarCorrect
Why the other options are incorrect
- Option A
This is a correct match, so it cannot answer a question asking for the incorrect pair. The Ministry of Defence identifies HQ 3 Corps at Rangapahar Military Station, Dimapur, in Nagaland.
- Option B
This is a correct match: 4 Corps is based at Tezpur in Assam. Do not confuse this northeastern headquarters with the northern formations based in Ladakh or Kashmir.
- Option C
This is a correct match: 14 Corps, also known as Fire and Fury Corps, is headquartered at Leh. The question requires the mismatch, not a headquarters that is correctly located in the Himalayan region.
Q2Current Affairs·Defence, Space and Security in NewsPYQ 2026
Which of the following items of defence hardware is/are manufactured in India?
1. Su-30 MKI Fighter Jets
2. T-90 MK-III Tanks
3. Akula Class Submarine
Select the answer using the code given below:
- A1 and 2Correct
- B1 and 3
- C1 only
- D2 only
Why the other options are incorrect
- Option B
The Su-30MKI qualifies because HAL has a production line in India. Akula-class submarines do not: India acquired their use through a Russian lease, while the T-90 should have been included.
- Option C
HAL manufacture makes statement 1 correct, but it is not the only qualifying item. T-90 tanks are also produced in India; the question asks about manufacture, not whether the original design was wholly Indian.
- Option D
T-90 manufacture at Avadi makes statement 2 correct, but this option omits the HAL-built Su-30MKI. Licensed manufacture of a foreign-origin design still meets the wording “manufactured in India”.
Q3Current Affairs·Defence, Space and Security in NewsPYQ 2026
Consider the following statements about Mission Sudarshan Chakra of India:
1. It aims to enhance India’s air defence, ballistic missile defence and aerial offensive capabilities.
2. This Mission is being designed to enhance rapid, precise, and powerful defence responses, reinforcing India’s strategic autonomy.
3. One of the aims of this Mission is to cover all public places of India by an expanded nationwide security shield by 2035.
Which of the statements given above is/are correct?
- A1, 2 and 3Correct
- B1 and 2 only
- C2 and 3 only
- D1 only
Why the other options are incorrect
- Option B
Statements 1 and 2 are accepted, but the key also accepts statement 3. Its broad wording has an official basis: PIB’s summary uses “all public places” with a 2035 target, while the fuller speech names important civilian and strategic locations. Do not treat a target as an accomplished capability.
- Option C
Statements 2 and 3 are accepted, but this option omits statement 1. The announced initiative is a defence and response mission, not merely a civil-protection programme; its public-place coverage is a future policy aim.
- Option D
Statement 1 is accepted but is not the only accepted statement. The mission’s official announcement also stresses stronger, faster responses and an expanded security shield by 2035, including the public-place ambition stated in PIB’s summary.
Q4Current Affairs·Defence, Space and Security in NewsPYQ 2026
The Bureau of Indian Standard (BIS) recently introduced a national standard to test and assess bomb disposal system. Which of the following statements with regard to this system is/are correct?
1. The new standard is known as IS 19445: 2025.
2. It will improve interoperability of equipment across agencies.
3. It was developed by TBRL, DRDO in collaboration with the 30th Central Scientific Research Institute, Russia.
Select the answer using the code given below:
- A1, 2 and 3
- B2 and 3 only
- C1 and 2 onlyCorrect
- D1 only
Why the other options are incorrect
- Option A
Statements 1 and 2 are correct, but the claimed Russian co-development in statement 3 is not the account given in the official release. BIS formulated the standard following a request from the Ministry of Home Affairs and TBRL, DRDO.
- Option B
The interoperability benefit is correctly included, but the Russian-institute claim should be excluded. This option also wrongly omits statement 1, which gives the standard’s correct identifier, IS 19445:2025.
- Option D
The identifier is correct, but the standard also supports coordination across agencies through uniform performance benchmarks. Therefore statement 2 must be included alongside statement 1.
Q5Current Affairs·Defence, Space and Security in NewsPYQ 2025

Explanation
Correct. CL-20, HMX and LLM-105 are all high-energy explosive compounds studied and used for advanced military munitions.
Why the other options are incorrect
- Option A
CL-20, HMX and LLM-105 have no connection to refrigerant technology.
- Option C

Rocket propellants are a different class of chemicals; these are military-grade explosives.

Why the other options are incorrect
- Option A
Statement 1 is incorrect because Mitra Shakti is the India-Sri Lanka joint exercise, not India-Bangladesh.

Statement 1 is incorrect; the exercise partner is Sri Lanka, not Bangladesh.

The fuel type (uranium vs thorium) is not the determining factor for IAEA safeguards applicability in India.
- Option C
No Indian nuclear reactors are operated by foreign enterprises; the distinction is about fuel source, not operator nationality.
- Option D
India does not have privately-owned nuclear reactors; all are state-run under the Atomic Energy Act.
