Who was the last king of Satavahana dynasty?
Simuka
Yajna Sri Satakarni was the last king of the Satavahana dynasty. He ruled during the 2nd century CE and played a significant role in the later stages of the dynasty. Why option (C) fits: The Satavahana dynasty was one of the most prominent Indian dynasties in the Deccan region, and Yajna Sri Satakarni is recognized as the last monarch of this dynasty. Eliminations: (A) Samudragupta and (B) Vikramaditya Maurya are not part of the Satavahana dynasty, while (D) Simuka was one of the early rulers of the Satavahanas, but not the last.
Placing each ruler in his correct dynasty first makes it clear which one even belongs to this question.
Since the dynasty's founder and its last effective ruler are different people, and the question asks for the latter, the answer is Yajna Sri Satakarni.
Hence, the correct answer is Yajna Sri Satakarni.
