Which Mughal Emperor died while climbing down the stairs of his library?

Humayun

The correct answer is Option 3- Humayun

Mughal Emperor Humayun died while climbing down the stairs of his library.

On January 24, 1556, Humayun was walking down the stairs of his library in the Sher Mandal pavilion in the Red Fort complex in Delhi when he slipped and fell, hitting his head on a stone railing. He died of his injuries three days later.

Humayun's death was a tragedy for the Mughal Empire. He was a wise and benevolent ruler, and he had done much to consolidate the Mughal Empire in India. His son, Akbar, went on to become one of the greatest Mughal emperors.
