Which one of the following is a very significant aspect of the Champaran Satyagraha?

1. The question asks for a very significant aspect of the Champaran Satyagraha (1917). 2. Option (A) is partially true (some lawyers were involved) but exaggerates the scale. While figures like Rajendra Prasad were present, Champaran did not see active all-India participation of these groups to the extent seen in later movements. It was primarily focused locally. 3. Option (B) is incorrect. While the movement involved peasants, it wasn't specifically characterized by the active involvement of Dalit and Tribal communities as its defining feature across India. 4. Option (C) is correct. The Champaran Satyagraha, led by Mahatma Gandhi, was the first major experiment in satyagraha in India focused on the grievances of indigo farmers (peasants) against planters. Its success marked a crucial turning point, demonstrating the effectiveness of non-violent resistance and directly linking peasant unrest and agrarian issues to the broader India's National Movement. 5. Option (D) is incorrect. While the Satyagraha led to the abolition of the exploitative tinkathia system, it did not cause a drastic decrease in the overall cultivation of plantation crops and commercial crops across India.
