Boycott of government schools and courts shows which common strategy of non-cooperation?

Correct answer: Withdrawing cooperation from colonial institutions

The governing concept is institutional boycott as a form of Non-Cooperation. Government schools and courts were important parts of the colonial administrative and social system. Refusing to attend or use them was intended to withdraw Indian participation and encourage alternative national institutions. Therefore option A is correct. The boycott did not educate British rule, expand foreign trade, or strengthen colonial institutions; it challenged their authority.
