Answer:
The most aggressive revolt of the Indian National Congress was the Salt Strike.
Explanation:
The Salt Strike was a political demonstration in India in 1930, led by Mahatma Gandhi and was an important part of the Indian Independence Movement. It was a direct action, containing a tax action and a non-violent action aimed at the British salt monopoly in British India.
The British colonial power had a monopoly on the manufacture and sale of salt and the proceeds helped to finance the public sector of British India. For many Indians, this monopoly was the only tax they paid, as few of them paid income tax and there was no value added tax or import duty.
The salt monopoly became a symbol of British rule in India. Gandhi, along with a number of followers, traveled a distance of 400 km so that they could then start producing salt at the coast.
