Option c is the correct answer. In the mid-eighth century, Dantidurga, a Rashtrakuta chief, overthrew his Chalukya overlord and performed a ritual called hiranya-garbha (literally, the golden womb). The Hiranya-Garbha ritual was a Vedic ritual that was performed by kings to legitimize their rule. The ritual involved the king being placed in a golden womb and then being reborn as a Kshatriya, the warrior caste. This ritual was believed to give the king the power and authority to rule.
