Correct answer: B
Explanation
The First Battle of Panipat was fought on 21 April 1526, so its 500th anniversary fell on 21 April 2026. Babur defeated Ibrahim Lodi, the last Sultan of Delhi, using cannons and the tulughma flanking tactic, which ended the Lodi dynasty and founded the Mughal Empire. Babur's clash with Rana Sanga was at Khanwa in 1527, and the Second Battle of Panipat (Akbar's forces versus Hemu) was in 1556.
