An Assertion (A) and a Reason (R) are given below. Assertion (A):…

Concept: An Assertion-Reason item needs three separate judgments: (1) is the Assertion (A) true on its own, (2) is the Reason (R) true on its own, and (3) — only if both are true — does R state the actual cause behind A, or is R merely a second true fact that happens to sit alongside A without explaining it.

Application: Applying this to Mohammad-bin-Tughlaq:

1. Check A: 'Wisest fool' is the standard epithet historians use for him — it is a true characterization, not a fabricated one.

2. Check R: 'Wise plans, foolish implementation' is also true and is documented by specific measures — moving the capital to Daulatabad (a sound strategic aim to secure control over the Deccan, but a disruptive forced relocation in practice) and the token currency (a sound monetary idea, undone by forgery and poor rollout).

3. Check the link: the epithet in A exists precisely BECAUSE of the pattern in R — sound conception undone by flawed execution is the reason he earned that label, not an unrelated coincidence. So R explains A.

Cross-check against the near-miss options:

• 'A correct, R false' fails — R's claim (wise plans, foolish execution) is itself well documented, so it cannot be false.

• 'A false, R correct' fails — A's claim (the epithet) is the standard historical characterization, so it cannot be false.

• 'Both correct but R does not explain A' fails — the failure pattern in R is exactly why the epithet in A is applied; the two are causally linked, not just two independent facts.

Both A and R are true, and R is the appropriate explanation of A.
