Zero mK India Private Limited, the start-up that will develop the dilution refrigerator with DRDO, is based in which state?

The correct answer is the Technology Development Fund. DRDO signed the agreement for an indigenous 20 mK dilution refrigerator with the start-up Zero mK India Private Limited under the TDF scheme, and it is the first high-value deep tech project agreement the scheme has supported. The funding flows from the Rs 500 crore corpus that Raksha Mantri Shri Rajnath Singh had cleared for deep tech and cutting-edge projects. Option B is wrong because the Innovations for Defence Excellence framework is a separate route that backs innovators through challenges and prototype grants, and it was not named in this signing. Option C is wrong because the Make-II procedure is a capital procurement category meant for industry-funded prototype development, not the vehicle used here. Option D is wrong because the Defence Testing Infrastructure Scheme pays for shared test facilities rather than for a cryogenic product development agreement with a start-up.

The correct answer is the National Quantum Mission. A dilution refrigerator of the 20 mK class produces the ultra-cold millikelvin environment in which quantum computing platforms and related quantum technologies are operated and tested, so building one in India directly serves the quantum mission and strengthens capability in quantum technology, advanced cryogenics and strategic technologies. It also trims dependence on imported cryogenic infrastructure. Option A is wrong because the supercomputing mission builds classical high performance computing systems, which do not need millikelvin cooling. Option C is wrong because the green hydrogen mission deals with electrolysers and hydrogen production rather than cryogenic quantum hardware. Option D is wrong because the ocean mission covers deep sea exploration and manned submersibles, an unrelated domain. The agreement therefore reads as a quantum ecosystem step, not a computing, energy or marine one.

The correct answer is submarine rescue certification, which the announcement does not mention at all. What it does list are professional engagements in harbour and at sea of three kinds: cross-deck visits, in which sailors of one navy go aboard the other's ship; operational interactions, in which the two crews compare their drills and procedures; and sporting engagements between the ships' companies. Through these the two navies expect to share experience and best practices, raise their interoperability and build mutual understanding. Options A, B and C are therefore all named in the release and cannot be the answer to a question framed in the negative. Questions of this form reward careful reading of a short release, because the wrong option is usually something that sounds thoroughly naval and would fit an exercise of this kind, yet is simply absent from the text.

The correct answer is France. VARUNA is the naval exercise that India holds with the French Navy, and the supporting detail in this announcement points the same way, since the Indian ship has berthed at Toulon, a French port on the Mediterranean, for the harbour and sea phases of the exercise. The announcement also frames the visit as a sign of an enduring maritime partnership between India and France and of cooperation between them that keeps widening. The other options name countries with which India does conduct naval exercises, which is exactly why they are placed here as distractors, and a candidate who remembers only that the exercise is bilateral, or who recalls the name without the partner, has no way to choose. Tie the name of the exercise to the partner navy, and the port to the partner as well.

The correct answer is the 24th edition. The Ministry of Defence announcement names the edition explicitly, and it is the single most asked detail about a recurring exercise, because the number records how far back the series goes and distinguishes this year's round from every earlier one. Options B and D sit on either side of the right answer and are the classic way of testing whether a candidate has read the number or merely recognised the name of the exercise. Option A is easy to pick for a different reason, since the ship reached the port on the twenty-second day of the month, and a date and an edition number that look alike are readily swapped in memory. Keep the two apart: the edition is the 24th, while 22 September 2026 is the day of arrival at Toulon.
