Correct option is D
The Bengal Partition of 1905 by the British was a significant event that intensified the Extremists' disillusionment with the British colonial rule.
The Extremist leaders, including Bal Gangadhar Tilak, Lala Lajpat Rai, and Bipin Chandra Pal, strongly opposed this move, seeing it as a strategy of divide and rule.
The partition was reversed in 1911 after widespread protests, but its impact on the Indian national movement, especially the Extremist leaders, was profound.
The partition was also significant in terms of its long-term consequences for Indian society, as it fueled religious divisions that would later have a lasting impact on the Indian subcontinent.
