Which emperor did Bheema defeat in order to enable Yudhistra to perform the Rajasuya Yagna?

To solve this question, the user needs to have knowledge of the Indian epic, Mahabharata. The Rajasuya Yagna is a significant event in the epic, and Bheema plays a key role in it.

Now, let's go through each option and explain why it is right or wrong:

A. Kritavarma: This option is incorrect because Bheema did not defeat Kritavarma to enable Yudhistra to perform the Rajasuya Yagna. Kritavarma was a Yadava prince and a friend of Krishna who fought on the side of the Kauravas in the Kurukshetra War.

B. Shishupala: This option is incorrect because Bheema did not defeat Shishupala to enable Yudhistra to perform the Rajasuya Yagna. Shishupala was a king of the Chedi kingdom and a cousin of Krishna who was slain by him at the event.

C. Jarasandha: This option is correct. Bheema defeated Jarasandha, the king of Magadha, to enable Yudhistra to perform the Rajasuya Yagna. Jarasandha was a powerful king who had defeated many other kings in battle and had imprisoned them. In the epic, Bheema fights a long and grueling battle with Jarasandha and finally defeats him by tearing him in half with his bare hands.

D. None of the above: This option is incorrect because option C, Jarasandha, is the correct answer.

The Answer is: C
