The answer is C) his lack of religious toleration caused widespread dissatisfaction with the majority of the population
Unlike his predecessors who were sensitive in ruling a largely Hindu population, Aurangzeb was seen as a more 'religious' leader who wanted to impose some of his own beliefs on his subjects.
However, in reality many historians actually dispute this. While he did destroy some Hindu temples, the number is often exaggerated and it should be noted that he also destroyed mosques.
