Who among the following formed the Bihar Provincial Kisan Sabha in 1929?

The correct answer is Swami Sahajanand Saraswati.

Step-by-Step Explanation:

1. Context of the Kisan Movement in Bihar:
During the late 1920s, the peasant movement (Kisan movement) in India was gaining momentum to address the grievances of tenant farmers against the oppressive landlord (zamindari) system, high rent, evictions, and forced labor.

2. Formation of the Bihar Provincial Kisan Sabha:
To organize the peasants and give a structured voice to their demands, the Bihar Provincial Kisan Sabha (BPKS) was formed in 1929.

3. Role of Swami Sahajanand Saraswati:
Swami Sahajanand Saraswati was the pioneering leader who founded the Bihar Provincial Kisan Sabha in 1929. He was elected as its President, and Shri Krishna Sinha became its Secretary. The organization successfully mobilized peasants across Bihar, leading to a massive social reform and political movement.

4. Analysis of other options:
- Jayprakash Narayan: A prominent socialist leader who was actively involved in the nationalist movement, the Congress Socialist Party, and the Total Revolution, but was not the founder of the BPKS in 1929.
- JM Sengupta: A leader from Bengal associated with the Indian National Congress and the non-cooperation movement, not the peasant movement in Bihar.
- Kunwar Singh: A notable leader of the Indian Rebellion of 1857 from Jagdispur, Bihar, who lived much earlier than the 1929 peasant mobilization.
