Option b is the correct answer. Statement I is correct- The Zamindars were an exploitative class in Mughal India. The Zamindars were a hereditary landowning class who collected revenue from peasants on behalf of the Mughal administration. They often wielded significant power and could exploit the peasants through excessive taxation or other forms of coercion. Statement II is correct- The Zamindars often received the support of the peasantry in a large number of agrarian uprisings in North India in the 17th century. While it is true that some agrarian uprisings involved collaboration or support from certain sections of the peasantry, it is not a universal or consistent pattern. Agrarian uprisings can have complex dynamics, and the peasantry's relationship with the Zamindars varied across different regions and contexts.
