The link between Kumaragupta I and Nalanda shows which deeper feature of the Gupta age?

Correct answer: Patronage of intellectual institutions

The direct answer is B: the link shows patronage of intellectual institutions. Nalanda became a major centre of learning, debate and Buddhist as well as wider intellectual study. Kumaragupta I is traditionally associated with its foundation or early support, although the institution developed over time under several rulers. This association suggests that the Gupta age could support organised education and centres of knowledge. B is correct because it identifies institutional patronage, not merely personal learning. A is wrong because Nalanda was not evidence of market control. C is wrong because this association does not show that the capital was transferred. D is wrong because it does not prove naval conquest. A careful student should remember that Nalanda's growth was gradual and involved later patrons too; the question asks for the broad feature shown by the association. Memory cue: Kumaragupta and Nalanda point to learning, scholarship and patronage.
