The correct option is C Alauddin Khilji
During the reign of Alauddin Khilji, the Delhi Sultanate ventured into the southern region of the subcontinent for the first time. Khilji's trusted general, Malik Kafur, led the expeditions. One after the other, kingdoms all the way to Madurai fell to the wrath of Kafur and his army, and were subsumed within the Sultanate.
