Which of the following Rebellion occurred between 1855-56?

Correct option is C

The correct answer is (c). The Santhal Rebellion occurred between 1855 and 1856. It was a major tribal uprising against the British in the Chota Nagpur region of India.
The Santhals are a tribal group concentrated in the state of Jharkhand. This was the first major peasant revolt in India. The revolt was a reaction to oppressive practices by the zamindars, moneylenders, Europeans, and British government officials who raised land taxes and exploited farmers.
The Santhals formed their own armies composed of peasants marching against their oppressors. The rebels were led by the four Murmu brothers - Sidhu, Kanhu, Chand, and Bhairav. The rebellion was suppressed by the British in 1856, but it had a significant impact on the British Raj.
