Read the assertion and reason. Assertion: The First World War increased discontent in India. Reason: The war increased taxes, inflation, and recruitment pressure. Choose the correct option.

Correct answer: Both assertion and reason are true, and the reason correctly explains the assertion.

Both parts are historically correct, and the reason explains the assertion directly. During the First World War, the colonial government increased taxes and forced recruitment, while shortages and wartime demand contributed to sharp price rises. These economic burdens affected ordinary people and deepened resentment against British rule. Since the stated pressures were important causes of the growing discontent, option A is the correct assertion-reason relationship; the other options wrongly separate or reject true statements.
