Explanation:

- Razia Sultan was the daughter of Shamsuddin Iltutmish and ruled as a Sultan of Delhi.

- After Razia Sultan, her brother Bahram Shah became the ruler, not Ghiyasuddin Balban immediately. Balban came to power later.

- Option 1: Shamsuddin Iltutmish – He was Razia's father, but he ruled before her, not after her.

- Option 2: Ghiyasuddin Balban – He ruled much later, after a few other successors.

- Option 3: Prithviraj Chauhan – He was a ruler before the Delhi Sultanate era and never ruled after Razia Sultan.

- Option 4: Qutbuddin Aibak – He established the Mamluk dynasty but ruled long before Razia Sultan.

- The correct answer is none of these options, as Bahram Shah succeeded Razia. But from given choices, none are correct for directly after Razia Sultan.
