Explanation:

Ghatotkacha was a son of Gupta, the founder of the Gupta dynasty. Like his father, Ghatotkacha is not attested by his own inscriptions. The earliest description of him occurs in his grandson Samudragupta's Allahabad Pillar inscription, and is repeated verbatim in several later records of the dynasty. Earlier scholars attributed a gold coin and a clay seal to him, but these are now unanimously assigned to Ghatotkacha-gupta, who was a son or a younger brother of the 5th century Gupta ruler Kumaragupta I.
