Option d is the correct answer. The idol inscribed with the name Manibhadra (Yaksha) was found from the place called Parkham. This statue, known as the "Parkham Yaksha," was discovered near Mathura and is datable to the period between 200 BCE and 50 BCE. The statue stands at 2.59 meters high and features an inscription that identifies it as representing the Yaksha Manibhadra. The inscription indicates that it was made by Gomitaka, a pupil of Kunika, and set up by eight brothers who were members of the Manibhadra congregation ("puga"). This significant find provides insights into the artistic and cultural influences of the time.
