The correct answer is: D. 1878 AD
The Land Movement in Sirmaur was a peasant uprising that took place in 1878 in the princely state of Sirmaur in present-day Himachal Pradesh, India. The uprising was led by a peasant named Thakur Chandu Lal, who was opposed to the high taxes and oppressive land tenure system imposed by the state government. The uprising was suppressed by the state government, but it led to some reforms, including a reduction in taxes and an improvement in the land tenure system.
The Land Movement in Sirmaur was part of a larger wave of peasant uprisings that took place in India in the 19th century. These uprisings were a response to the growing economic and social inequality that was being caused by British colonial rule. The Land Movement in Sirmaur was one of the most successful of these uprisings, and it had a significant impact on the history of the state of Sirmaur.
