The statement that best describes the British response to the Salt March is:
The British responded to the Salt March by jailing the protestors and ending the salt tax.
While the British maintained control over India and did not formally end their overall political and economic control, they did respond to the Salt March by arresting many leaders, including Mahatma Gandhi, and eventually repealed the salt tax in response to the civil disobedience campaign. However, it is important to note that the repeal was more of a tactical response and did not signify a broader change in British policy in India.
