What important step did Congress take for the Non-Cooperation Movement at the Nagpur session?

Correct answer: It reorganised itself for a mass movement

At the Nagpur session in 1920, Congress adopted organisational changes that made it more suitable for a broad-based mass movement. Its structure and methods were adjusted to increase participation beyond a small group of educated leaders, helping workers, peasants and other sections join the national struggle. Therefore option A is correct. The other choices contradict Congress’s decision to launch and expand non-cooperation.
