Answer: Option D
Answer: (d)
His weak nature was not a reason for Balban abandoning the policy of conquest and adopting the policy of consolidation. Ghiasuddin Balban is the greatest Sultan of the Slave dynasty and an extremely shrewd military chief. He belonged to the Ilbari tribe of a well-to-do Turk family.
But unfortunately, he was captured by the Mongols and sold to Khwajah Jamal-ud-din Basri in Baghdad and later brought to Delhi by Iltutmish, who purchased him as a slave.
Balban, well aware of Bengal affairs and the activities of its governors, was determined to curb their power and keep them under control. With his end in view, the sultan appointed his trusted and tried slave Tughral as a deputy of Amin Khan, governor of Bengal.
