Who ruled over Delhi after Razia Sultan?

The correct answer is Option 2- Ghiyasuddin Balban

Razia Sultan was the only female ruler of the Delhi Sultanate. She ruled from 1236 to 1240, and her reign was marked by conflict and instability. She was eventually killed by a group of nobles who were opposed to her rule.

After Razia Sultan's death, her brother, Muhammad, succeeded her. However, Muhammad was a weak ruler, and he was soon overthrown by Balban. Balban ruled for 21 years, and he was a successful ruler who expanded the Delhi Sultanate and strengthened its military.
