The correct answer is C. Khanwa.
The Battle of Khanwa was fought on 16 March 1527 between the Mughal emperor Babur and the Rajput ruler Rana Sanga of Mewar. The battle was fought near the village of Khanwa, about 100 km (62 mi) from Agra, in the present-day state of Uttar Pradesh, India.
Babur had invaded India in 1526 and defeated the Lodhi dynasty at the First Battle of Panipat. Rana Sanga was the most powerful Rajput ruler of the time and he had formed a confederacy of Rajput states to oppose Babur.
The battle was a decisive victory for Babur. Rana Sanga was killed in the battle and his confederacy was broken. This victory paved the way for the Mughal conquest of India.
Option A is incorrect because the First Battle of Panipat was fought in 1526. Option B is incorrect because the Battle of Chunar was fought in 1539. Option D is incorrect because the Battle of Jaunpur was fought in 1530.
