During the reign of which Viceroy, did the ‘Salt March’ take place?

The correct answer is Option 3- Lord Irwin

The Salt March took place during the reign of Lord Irwin, the Viceroy of India from 1926 to 1931.

The Salt March was a non-violent protest against the British salt tax, which was a heavy burden on the poor Indian people. The march was led by Mahatma Gandhi, and it began on March 12, 1930, from Sabarmati Ashram in Gujarat. Gandhi and his followers marched 240 miles to the coastal town of Dandi, where they made salt from seawater.

The Salt March was a major turning point in the Indian independence movement. It showed the power of non-violent resistance, and it inspired millions of Indians to join the struggle for independence. The Salt March also helped to raise Gandhi's profile as the leader of the Indian independence movement.
