Explanation:

Balban adopted the policy of consolidation for several reasons, including:

1.Threat of external invasion, particularly from the Mongols.

2.Internal revolts and challenges to his authority.

3.The desire to maintain control over Indian kings and territories under Turkish rule.

Balban's consolidation policies were aimed at ensuring peace, protection, and the stability of the empire. His strong and authoritarian rule was a response to the challenges he faced during his reign.
