Correct answer: C. Subhas Chandra Bose
Explanation: The direct answer is C, Subhas Chandra Bose. The Forward Bloc was founded by Subhas Chandra Bose in 1939 after he left the leadership of the Indian National Congress. He wanted to bring together progressive and left-leaning forces and continue a more forceful struggle for complete independence. Option A, Jawaharlal Nehru, is wrong because he was a major Congress leader but did not found the Forward Bloc. Option B, Sardar Patel, is wrong because he was an important Congress organiser and national leader, not the founder of this organisation. Option C, Subhas Chandra Bose, is correct because he established the All India Forward Bloc. Option D, Rajendra Prasad, is wrong because he later became the first President of independent India and was not the founder of the Forward Bloc. The key method in such questions is to connect an organisation with its founder instead of guessing from general fame. Memory cue: “Forward Bloc moves forward with Bose.”
