Which action was part of the Non-Cooperation Movement?

Correct answer: Boycott of foreign goods

The governing concept is non-cooperation with colonial institutions and markets. Participants rejected foreign cloth and other imported goods, promoted swadeshi products, and withdrew support from selected colonial institutions. Therefore option A correctly identifies an action of the movement. Demanding British titles, supporting the repressive Rowlatt Act, and praising colonial rule would cooperate with imperial authority rather than challenge it.
