Who formed the Bihar Socialist Party?

Correct option is B

The Bihar Socialist Party, established within the Congress in 1931, was founded on Marxist-Leninist socialist principles. Initiated by Phulan Prasad Varma with JP Narayan's leadership, the party was a collective effort. In July 1931, figures such as Ganga Sharan Sinha, Rambriksh Benipuri, Phulan Prasad Varma, and Ramanand Mishra came together to form the Bihar Socialist Party. This group laid the groundwork for the creation of the Congress Socialist Party in 1934, marking a significant moment in the political landscape. The party's primary goals included the spread of socialist ideologies, the establishment of labor and peasant organizations, and the broader dissemination of its principles among the masses. An executive committee was also formed to steer the party's direction, with Abdul Bari serving as President, Ganga Sharan Sinha and PP Verma as Secretaries, and Ambika Kant Sinha as the Treasurer, ensuring the party's organized and strategic approach to achieving its objectives.
