The correct option is publicly violating Salt Law at Dandi.

On March 12, 1930, Mahatma Gandhi launched the historic Civil Disobedience Movement with the Dandi March. Along with 78 of his chosen followers, he walked from his Sabarmati Ashram to the coastal village of Dandi in Gujarat.
On April 6, 1930, Gandhi reached Dandi, picked up a handful of natural salt, and technically broke the salt laws imposed by the British Raj, which gave the government a monopoly on salt manufacturing and taxation.

After committing this act of civil disobedience, Gandhi declared: "Sedition has become my religion." By this, he meant that opposing the unjust and exploitative British colonial rule (which the authorities categorized as "sedition") was no longer just a political act, but a moral and spiritual duty.
