Correct Option: A

Dantidurga, the Rashtrakuta rulers, is known to have made the 'Hiranya-garbha-dana' at Ujjaini. Rashtrakutas were subordinate to the Chahlukyas. Dantidugra, a Rashtrakuta chief, threw his Chalukyan overlord and performed Hiranya-garbha, a ritual that is thought to lead to the rebirth of the sacrifice as a Kshatriya. Dantidurga, thus, founded the Rashtrakuta empire.
