The correct option is B Rashtrakutas
The Rashtrakutas became the Samantas for the Deccan region, which was ruled by the Chalukyas. Dantidurga was a Rashtrakuta leader who decided that he wanted to be more than a Samanta, and overthrew the Chalukyas. He established himself as the ruler of the deccan region of the Chalukyas, after performing a ritual called the Hiranyagarbha.
