The correct answer is: a) Women-led peasant agitations.
The Nupi Lan (Naga Women’s War) was a women-led uprising against the British colonial government in Manipur, India, in 1939. The uprising was sparked by the British government’s decision to conscript Manipuri men into the Indian Army to fight in World War II. The women of Manipur, led by Rani Gaidinliu, protested the conscription and demanded that the British government withdraw its troops from Manipur. The uprising lasted for several months and resulted in the deaths of hundreds of people. The British government eventually agreed to withdraw its troops from Manipur, but the Nupi Lan had a lasting impact on the history of Manipur.
Option b) is incorrect because the Nupi Lan was not an armed tribal rebellion. The uprising was led by women, not by tribal leaders.
Option c) is incorrect because the Nupi Lan was not a labor union strike. The uprising was not related to labor issues.
Option d) is incorrect because the Nupi Lan was not a religious reform movement. The uprising was not related to religious issues.
