The correct answer is Bhagat Singh.
Bhagat Singh raised the slogan Inquilab Zindabad, meaning Long Live the Revolution, during the freedom struggle. He famously shouted this slogan along with Batukeshwar Dutt inside the Central Legislative Assembly in Delhi in 1929 while throwing pamphlets after a bomb blast, without harming anyone.
The phrase itself was originally coined by the Urdu poet Hasrat Mohani, but it became a mass revolutionary cry mainly because of Bhagat Singh's use of it.
