Correct answer: B. Ram Singh Kuka
Explanation: The direct answer is B: Ram Singh Kuka. The Kuka Movement, also called the Namdhari Movement, arose in nineteenth-century Punjab. Its followers were known for religious reform, social discipline, opposition to some colonial practices, and patriotic resistance. Ram Singh was the principal leader associated with organising and guiding this movement. Therefore the reasoning is: identify the movement as Kuka or Namdhari; recall its leading figure; match Kuka Movement with Ram Singh Kuka. Option A, Birsa Munda, was the important tribal leader of the Munda Ulgulan in the Chotanagpur region, not the Kuka Movement. Option B is correct because Ram Singh led the Kuka or Namdhari movement. Option C, Raj Kumar Shukla, is remembered for bringing Mahatma Gandhi to Champaran and is connected with the Champaran movement, not Kuka resistance. Option D, Gomdhar Konwar, was associated with the Ahom revolt in Assam, not Punjab’s Kuka Movement. A useful memory cue is: Kuka or Namdhari movement—Ram Singh Kuka; do not confuse him with Birsa Munda or Gomdhar Konwar, who belonged to different regional struggles.
