Which of the following factors contributed to the formation of the Forward Bloc by Subhas Chandra Bose in 1939?
1. Bose failed to win the confidence of Mahatma Gandhi.
2. The Congress Left was disunited and failed to support Bose.
3. The Communists did not support Bose in his endeavours.
4. The supporters of M.N. Roy and socialist leaders like Jayaprakash Narayan preferred Congress unity to supporting Bose.
Select the answer using the code given below:

Subhas Chandra Bose resigned from the presidency of the Indian National Congress in April 1939 and subsequently formed the Forward Bloc. The factors leading to this included:

• Statement 1 is correct: Following the Tripuri session, Bose failed to win the confidence of Mahatma Gandhi, who refused to suggest names for the Congress Working Committee, making it impossible for Bose to function effectively.
• Statement 2 is correct: The Congress Left was highly disunited. Bose had hoped to consolidate the left-wing forces against the right-wing leadership, but the left groups failed to present a united front.
• Statement 3 is incorrect: The Communists did support Bose in his initial endeavours. They backed him in the presidential election against Pattabhi Sitaramayya and voted against the Pant resolution at the Tripuri session, standing by Bose when others retreated.
• Statement 4 is correct: Leaders of the Congress Socialist Party (like Jayaprakash Narayan) and the Royists (supporters of M.N. Roy) abstained during the crucial Pant resolution vote. They preferred maintaining Congress unity under Gandhi's leadership for the broader anti-imperialist struggle over supporting Bose's confrontational approach.

Thus, statements 1, 2, and 4 are correct.
