Correct answer: (b) Both (A) and (R) are true, but (R) is not the correct explanation of (A)
Explanation
- A
Both (A) and (R) are true and (R) is the correct explanation of (A)
(a) Both true and (R) explains (A). Akbar did follow Sher Shah in trimming the trimetallic system, and the dam was the chief copper piece—but naming the dam does not by itself explain why he regulated currency. The stored key therefore refuses (R) as the explanation.
- B
Both (A) and (R) are true, but (R) is not the correct explanation of (A)
(b) Both true, but (R) is not the correct explanation of (A). Sher Shah’s rupee–dam trimetallism was continued and standardised under Akbar (including the jalali and ilahi experiments). The dam as copper unit is true, yet it is a detail of the system, not the reason he chose to regulate minting. Parallel truths, not cause.
- C
(A) is true, but (R) is false
(c) (A) true, (R) false. (R) is not false: 40 dams = 1 rupee is the standard Akbari copper relation inherited from Sher Shah.
- D
(A) is false, but (R) is true
(d) (A) false, (R) true. (A) is not false: Ain-i-Akbari and mint lists show deliberate currency regulation.
Summary. Official key is (b). Both (A) and (R) are true, but (R) does not explain (A). Akbar regulated coinage in Sher Shah’s tradition; the dam was the chief copper coin. That copper fact does not cause the policy of regulation. Honour the stored letter (b).
