The correct answer is Subhas Chandra Bose.
Netaji, meaning respected leader, is the title given to Subhas Chandra Bose, one of the most prominent leaders of the Indian freedom struggle. He founded the Indian National Army (Azad Hind Fauj) to fight British rule with armed resistance.
Bose is remembered for his famous call, Give me blood, I will give you freedom. He also formed the Provisional Government of Free India in Singapore in 1943. His disappearance in 1945 after a reported plane crash remains a debated topic in Indian history.
