Correct answer: (d) (A) is false, but (R) is true.
Explanation
- A
Both (A) and (R) are true and (R) is the correct explanation of (A).
Both true and R explaining A cannot stand, because Assertion is false: collective responsibility is to the Lok Sabha, not to both Houses. Even though R is true, it does not make A true or explain a false A. This code requires a true A.
- B
Both (A) and (R) are true, but (R) is not the correct explanation of (A).
Both true but R not explaining A still needs A to be true. Collective responsibility to Rajya Sabha as well is not the constitutional rule. A is false, so this option fails.
- C
(A) is true, but (R) is false.
A true and R false would invert the facts: A is the false limb and R is true (members of either House can be ministers, Article 75). This code is the wrong way round.
- D
(A) is false, but (R) is true.
(d) Official key: Assertion is false: the Council of Ministers is collectively responsible to the Lok Sabha only (Article 75(3)), not to the Rajya Sabha. Reason is true: members of both Houses are eligible to be Union ministers. Hence A is false and R is true.
Summary. Official key is (d). Collective ministerial responsibility in India runs to the Lok Sabha, which can pass a no-confidence motion; Rajya Sabha cannot. Eligibility to be a minister, however, extends to members of either House. Assertion therefore fails and Reason stands. The keyed AR code is A false, R true.
