Correct option is A
The
Santhal rebellion broke out in
1855. It was a significant uprising by the Santhal tribal community against the oppressive policies of the British colonial authorities and their allied landlords (zamindars). The rebellion, led by the Santhal leaders
Sidhu and
Kanhu Murmu, aimed to resist the exploitation and atrocities faced by the Santhal people due to land policies and high taxes. The movement eventually spread across the Santhal areas of present-day Jharkhand, West Bengal, and Bihar before being brutally suppressed by the British forces.
Thus, the correct answer is
(a) 1855.
