By whom the Kol Uprising was suppressed in Jharkhand region?

The correct answer is C. Camac.

The Kol Uprising was a major tribal rebellion against the British East India Company in the Kolhan region of Jharkhand, India, in 1831–32. The uprising was led by Sidho Kanhu, a Kol tribal leader. The British were able to suppress the uprising, but it led to a number of reforms in the way the British treated the tribal people of India.

Capt. Wilkinson was a British officer who was involved in the suppression of the Kol Uprising. He was not the main leader of the suppression effort, however. That role fell to Col. Camac.

Cliveland was a British officer who was not involved in the Kol Uprising.

Bayne was a British officer who was involved in the suppression of the Kol Uprising, but he was not the main leader of the suppression effort.
