Concept:The East India Company’s Diwani rights in 1765 shifted it from a trading body to a territorial ruler and changed how it paid for Indian goods.
Explanation:Statement (a) is correct: as Diwan, the Company became the chief administrator of Bengal, controlling revenue and governance.
Statement (b) is not a new conclusion: after 1765 the Company did administer land and organise revenue, but this was the result of Diwani, not a separate insight.
Statement (c) is false: before 1765 the Company imported bullion, not grain, from Britain to buy Indian goods.
