1540

The correct answer is Option 1- 1540

Sher Khan defeated Humayun at Kanauj in the year 1540.

This was the second major defeat suffered by Humayun at the hands of Sher Khan. The first defeat had occurred at the Battle of Chausa in 1539. After the defeat at Kanauj, Humayun was forced to flee India and take refuge in Persia. He was able to return to India and regain his throne in 1555.

The Battle of Kanauj was a decisive victory for Sher Khan and it marked the end of the Mughal Empire in India for the next fifteen years. Sher Khan founded the Suri dynasty and ruled India until his death in 1545.
