Correct answer: (d) (A) is true, but (R) is false.
Explanation
- A
Both (A) and (R) are true, but (R) is not the correct explanation of (A).
Option (a) claims both Assertion (A) and Reason (R) are true while (R) is not the correct explanation of (A). However, this is incorrect because the Reason contains a factual error regarding the missile's range.
- B
(A) is false, but (R) is true.
Option (b) claims that Assertion (A) is false and Reason (R) is true. This is factually inverted since the export of the BrahMos missile to the Philippines in April 2024 actually took place.
- C
Both (A) and (R) are true and (R) is the correct explanation of (A).
Option (c) claims both statements are true and (R) correctly explains (A). This fails because the stated range in the Reason is inaccurate for the exported variant, making the Reason factually false.
- D
(A) is true, but (R) is false.
Option (d) claims that Assertion (A) is true, but Reason (R) is false. This is the correct key because India indeed delivered the BrahMos Supersonic Cruise Missile systems to the Philippines in April 2024 under a landmark defence export deal, but the actual extended range of the export variant is capped around 290 kilometers, making the stated range of 490 kilometers in the Reason incorrect.
Summary. Official key is (d) because the assertion regarding the April 2024 delivery of the BrahMos missile to the Philippines is historically accurate, whereas the reason citing a range of 490 kilometers is incorrect. India completed this major defence supply agreement with the Philippines to bolster strategic ties and maritime security in the region. The export variant of the BrahMos supersonic cruise missile has a restricted range complying with international missile technology control norms, specifically around 290 kilometers. Therefore, Assertion (A) holds true while Reason (R) is false, validating option (d) as the correct choice.
