Correct Answer: Bhagat Singh

Solution : The correct option is Bhagat Singh.

During the struggle for India's independence from British colonial authority, Indian freedom fighter Bhagat Singh popularised his slogan "Inquilab Zindabad" (Long Live the Revolution). Bhagat Singh's use of the phrase, as well as his daring deeds, such as the nonviolent bombing of the Central Legislative Assembly, and subsequent trial, helped galvanise the Indian masses and raise attention to the independence cause.
