The correct answer is (c) Samudragupta.
The Asvamedha sacrifice was a Vedic ritual in which a horse was sacrificed to the god Indra. It was considered to be the most important of all sacrifices, and was only performed by kings who were considered to be great conquerors.
Samudragupta was a Gupta emperor who ruled from 335 to 375 CE. He is considered to be one of the greatest emperors in Indian history, and is known for his military conquests and his patronage of art and literature.
There is evidence that Samudragupta performed four Asvamedha sacrifices. This is recorded in the Allahabad Pillar inscription, which was erected by Samudragupta himself. The inscription states that Samudragupta “conquered the whole earth” and that he “performed four Asvamedha sacrifices.”
The other options are incorrect. Pusymitra Sunga was a Shunga emperor who ruled from 185 to 151 BCE. Pravarasena I was a Vakataka king who ruled from 270 to 335 CE. Kumaragupta I was a Gupta emperor who ruled from 415 to 455 CE. There is no evidence that any of these kings performed four Asvamedha sacrifices.
