The correct option is D Deccan
Aurangzeb fought a protracted war in the Deccan, where he spent the last 25 years of his life fighting. In 1652, Aurangzeb was again appointed as a governor of the Deccan. The Deccan produced poor tax revenue for the Mughals. As a youth in his previous term, Aurangzeb ignored the problem, allowing state-sanctioned corruption and extortion to grow. This time Aurangzeb set about reforming the system, but his efforts often placed additional burdens on the locals and were poorly received.
