In which year, did Babar defeat Sultan Ibrahim Lodi at the battle of Panipat?

The answer is B) 1526 AD. Babur defeated Sultan Ibrahim Lodi at the First Battle of Panipat on 21 April 1526, near modern Haryana. Ibrahim Lodi was killed, and the Delhi Sultanate ended, opening the way to the Mughal Empire. The battle is a classic example of how mobile artillery and the tulughma (flanking) tactic beat a larger but less organised army. This sits squarely in the Medieval History section, and in Mains it helps you explain how military technology reshaped political power in north India.

Why the others fail:

• 1527 AD: Babur's battle against Rana Sanga of Mewar at Khanwa, in March 1527. It is a different battle and a different opponent.
• 1525 AD: No Panipat battle. Babur was campaigning in Punjab in this period.
• 1524 AD: Babur's Punjab operations, including the attack on Lahore, with Daulat Khan Lodi involved. Again, not Panipat.

Trap: Candidates mix up Babur's three big victories (Panipat 1526, Khanwa 1527, Chanderi 1528). Anchor each one to its opponent: Lodi, Rana Sanga, Medini Rai.
