Why did the participation of different social groups make the Non-Cooperation Movement both powerful and complex?

Correct answer: Because it widened the mass base but the groups retained different demands

The governing concept is the diversity of participation in a mass nationalist movement. Peasants, workers, tribal communities, students, merchants and urban residents joined Non-Cooperation, giving it a much wider social and geographical base. However, each group connected the movement with its own local concerns, such as rent, labour restrictions or commercial interests. Option A is correct because it explains both its strength and its organisational complexity; the other options are factually contrary to this evidence.
