Correct answer: D. Rashtrakuta Dynasty
Explanation: The direct answer is D: the Rashtrakuta Dynasty. Dantidurga, also called Dantivarman in some historical references, is generally regarded in school-level Indian history as the founder of the Rashtrakuta dynasty. He established Rashtrakuta power in the Deccan in the eighth century, after defeating important regional rivals and building an independent kingdom. Option D is correct because Dantidurga is the ruler linked with the beginning of Rashtrakuta rule. Option A, the Pala dynasty, belonged mainly to eastern India and is associated with rulers such as Gopala. Option B, the Gupta dynasty, began much earlier and is associated with rulers such as Sri Gupta and Chandragupta I, not Dantidurga. Option C, the Chola dynasty, was a major southern dynasty, but Dantidurga is not regarded as its founder. The geographical clue is useful: connect Dantidurga with the medieval Deccan and the Rashtrakutas. Do not confuse a founder with a famous later ruler of the same period. Memory cue: “Dantidurga = Deccan Rashtrakuta founder.”
