The correct answer is option 3: Surya Sen. The Chittagong Armoury Raid was organised under his leadership. Surya Sen was a revolutionary freedom fighter from Bengal. He was a prominent member of the Indian National Congress and later joined the Indian Republican Army, a revolutionary organization. The Chittagong Armoury Raid was a significant event in India`s struggle for independence. It took place on 18th April 1930 in Chittagong (now in Bangladesh). A group of revolutionaries led by Surya Sen attacked the British armoury in order to capture weapons and ammunition. Although the raid was not entirely successful in terms of capturing the arsenal, it symbolized the spirit of resistance against British colonial rule. The actions of Surya Sen and his comrades played a crucial role in inspiring and motivating future generations of freedom fighters.
