The correct answer is A) Holkars.
The Holkars were a Maratha clan that established their rule over Indore in the 18th century. They were originally from the Deccan region of India, and they came to power under the leadership of Malhar Rao Holkar. Malhar Rao was a general in the Maratha army, and he played a key role in the Maratha victory over the Mughal Empire in the Battle of Panipat in 1761. After the battle, Malhar Rao established himself as the ruler of Indore, and he founded the Holkar dynasty.
The Holkars ruled Indore for over a century, and they were one of the most powerful Maratha clans. They were known for their military prowess, and they played a key role in the Maratha resistance to the British East India Company. The Holkars were eventually overthrown by the British in the early 19th century, but they left a lasting legacy on the region.
The other options are incorrect. The Scindias were a Maratha clan that ruled Gwalior, the Bhonsles ruled Nagpur, and the Gaekwads ruled Baroda.
