Consider the following statements: The Non-cooperation Movement led to the I. Congress becoming a mass movement for the first time. II. growth of Hindu Muslim unity. III. removal of fear of the British ‘might’ from the minds of the people. IV. British government’s willingness to grant political concessions to Indians. Of these statements

The Non cooperation Movement marked a significant shift in the Indian struggle for independence. Statement I is correct because Gandhi transformed the Congress from an elite group into a mass based organization by involving peasants and workers for the first time. Statement III is correct because the movement encouraged people to defy laws and face imprisonment, which effectively broke the psychological fear of British authority and their perceived invincibility.

Regarding the other points, while Hindu Muslim unity was visible during the movement due to the Khilafat alliance, it was temporary and did not lead to permanent communal harmony, making Statement II less definitive in a historical sense. Statement IV is incorrect because the British government did not show any immediate willingness to grant political concessions; instead, they responded with heavy repression and the movement ended without achieving its immediate goal of Swaraj. Therefore, Statements I and III are the primary and most accurate impacts of the movement.
