The correct option is C There was shortage of jagirs during Aurangzeb's reign.
Mansabdars received jagirs which were lot like iqtas. However, unlike the muqtis, mansabs did not reside or administer these jagirs. During the reign of Akbar, the jagirs were assessed carefully in order to be equal to the salary of mansabdars. However, the number of mansabdars increased during Aurangzeb's reign and there was shortage of jagirs.
