The correct answer is option 1, Ahmedabad. Gandhi started the ‘Dandi March’ from Ahmedabad. The ‘Dandi March’, also known as the Salt March or Salt Satyagraha, was a significant event in the Indian independence movement led by Mahatma Gandhi. It took place in 1930 as a protest against the British salt monopoly in India. Gandhi and a group of followers marched from Ahmedabad to the coastal village of Dandi, covering a distance of around 240 miles. The purpose of the march was to produce and sell salt in defiance of the British salt laws, which prohibited Indians from producing or selling salt. This march was symbolic of the nonviolent resistance and civil disobedience that Gandhi promoted as a means of achieving independence from British rule.
