The correct option is A Sabarmati
Mahatma Gandhi found in salt a powerful symbol that could unite the nation. On 31 January 1930, he sent a letter to Viceroy Irwin stating eleven demands. Some of these were of general interest; others were specific demands of different classes, from industrialists to peasants. The idea was to make the demands wide-ranging, so that all classes within Indian society could identify with them and everyone could be brought together in a united campaign. The most stirring of all was the demand to abolish the salt tax. Salt was something consumed by the rich and the poor alike, and it was one of the most essential items of food.
Mahatma Gandhi’s letter was, in a way, an ultimatum. If the demands were not fulfilled by 11 March, the letter stated, the Congress would launch a civil disobedience campaign. Irwin was unwilling to negotiate. So Mahatma Gandhi started his famous salt march accompanied by 78 of his trusted volunteers. The march was over 240 miles, from Gandhiji’s ashram in Sabarmati to the Gujarati coastal town of Dandi. The volunteers walked for 24 days, about 10 miles a day. Thousands came to hear Mahatma Gandhi wherever he stopped, and he told them what he meant by swaraj and urged them to peacefully defy the British. On 6 April he reached Dandi, and ceremonially violated the law, manufacturing salt by boiling sea water.
