In what wider context should the introduction of income tax and the rise in customs duties during wartime be understood?

Correct answer: As raising money from India for the colonial war economy

The governing concept is the financing of an imperial war economy. The First World War sharply increased the colonial government’s expenditure and demand for revenue. Raising income tax and customs duties allowed Britain to obtain more money from India and to make Indian consumers and producers bear part of the war cost. Thus, option A correctly identifies the wider context. The other choices incorrectly present taxation as self-government, peasant relief, or an action against the Khilafat Movement.
