Who presented the question of indigo cultivators of Bihar at the 1916 Lucknow session of the Indian National Congress?

Correct answer: (a) Rajkumar Shukla

Explanation

At the 1916 Lucknow Session of the Indian National Congress, a simple farmer from Bihar, Rajkumar Shukla, informed Gandhiji about the problem of indigo cultivators of Champaran and took a promise from him to visit Champaran. However, at the Lucknow Session of 1916, Braj Kishore Prasad of Darbhanga proposed the formation of a committee to investigate the problems of indigo cultivators and the atrocities of European planters, and it was passed unanimously. Therefore, the Champaran issue was discussed at the Lucknow Session of the Congress (1916).
