The correct answer to the question is option 2: Civil Disobedience Movement. The Dandi March, also known as the Salt Satyagraha, was a notable event during the Civil Disobedience Movement led by Mahatma Gandhi. The march took place in 1930 and involved a group of people led by Gandhi walking about 240 miles to the coastal town of Dandi in Gujarat. The purpose of the march was to protest against the British salt monopoly by making their own salt from seawater. This act of civil disobedience was a significant step towards India’s independence movement and gained widespread attention both within the country and internationally. It represented Gandhi’s strategy of nonviolent resistance and served as a symbol of the Indian people’s defiance against British colonial rule.
