According to Gandhi, why could British rule become weak without Indian cooperation?

Correct answer: Because Indian participation was necessary to run the government

The governing concept is the colonial dependence on cooperation and participation. Although ultimate authority rested with Britain, colonial administration relied on Indian employees, soldiers, taxpayers, consumers and institutions such as courts and schools. If people withdrew cooperation through boycotts and refusal to assist, the machinery of rule would lose effectiveness and legitimacy. Thus option A is correct; B, C and D are factually unrelated to Gandhi’s argument.
