The correct option is A Dandi March to break the Salt Laws
Gandhi inaugurated the Civil Disobedience Movement by conducting the historic Dandi Salt March starting from Sabarmati Ashram from where he went on to break the Salt Laws imposed by the British Government. Along with this activity, activities like no tax campaign, no revenue, and no rent (land tax) campaign became very popular in different parts of India. The movement was very intense in Bengal and the north-west.
