The correct answer is option 4, Lord Curzon. In 1905, the province of Bengal was partitioned into two parts by Lord Curzon, who was the Viceroy of India at that time. Lord Curzon believed that dividing Bengal along religious lines would help improve the administration of the province. This partition was met with widespread protests and opposition from the Indian National Congress, as it was seen as a move to weaken the nationalist movement by dividing Hindus and Muslims. The partition of Bengal was later annulled in 1911 due to the strong protests and the growing nationalist sentiments in India.
