The correct answer is Option 3- Iltutmish

Iltutmish organised his trusted nobles into a group of forty known as Turkan-i-Chahalgani.

The Turkan-i-Chahalgani, also known as the Forty, was a council of 40 Turkish and non-Turkish slaves who administered the Delhi Sultanate according to the wishes of Iltutmish. It was the first regular ministerial body in the history of the Indian subcontinent.

Iltutmish created the Turkan-i-Chahalgani to counter the power of the Turkish nobles, who he felt were a threat to his rule. The Forty were loyal to Iltutmish and helped him to consolidate his power.

The Turkan-i-Chahalgani played an important role in the administration of the Delhi Sultanate. They were responsible for a wide range of tasks, including military affairs, finance, and justice.

The Forty remained powerful even after Iltutmish's death. They played a major role in the succession of his son, Rukn-ud-Din Firuz. However, the Forty were eventually overthrown by Balban in 1266.
