The Wancho Revolt of 1942-43 was a significant uprising against:

British colonial rule
Ahom expansion
Missionary activities
Exploitative trade practices

The correct answer is: a) British colonial rule.

The Wancho Revolt of 1942-43 was a significant uprising against British colonial rule in the Wancho Hills of Nagaland, India. The revolt was led by a Wancho chief named Jadonang, who was inspired by the Indian independence movement and the teachings of Mahatma Gandhi. The rebels attacked British outposts and government buildings, and they also killed several British officials. The revolt was eventually suppressed by the British, but it had a significant impact on the history of Nagaland.

The other options are incorrect because:

  • Option b) is incorrect because the Ahoms were a pre-colonial kingdom that ruled over the Wancho Hills from the 13th to the 18th centuries. The Wancho Revolt of 1942-43 was a revolt against British colonial rule, not against the Ahoms.
  • Option c) is incorrect because missionary activities in the Wancho Hills did not begin until the late 19th century, well after the Wancho Revolt of 1942-43.
  • Option d) is incorrect because exploitative trade practices were a problem in the Wancho Hills, but they were not the primary cause of the Wancho Revolt of 1942-43. The revolt was primarily a reaction to British colonial rule.
