During the Salt March, when did Gandhiji begin to walk from his ashram at Sabarmati towards the ocean?

12 March 1930

The correct answer is Option (1) → 12 March 1930

"Where most Indians understood the significance of Gandhiji’s challenge, the British Raj apparently did not. Although Gandhiji had given advance notice of his “Salt March” to the Viceroy Lord Irwin, Irwin failed to grasp the significance of the action. On 12 March 1930, Gandhiji began walking from his ashram at Sabarmati towards the ocean. He reached his destination three weeks later, making a fistful of salt as he did and thereby making himself a criminal in the eyes of the law. Meanwhile, parallel salt marches were being conducted in other parts of the country."
