Exp) Option b is the correct answer.

The famous statement “Sedition has become my religion” was made by Mahatma Gandhi on 6th April 1930 at Dandi, when he broke the Salt Law as part of the Civil Disobedience Movement. This act marked a symbolic rejection of British authority and galvanized nationwide protests.

On 6th April, Gandhi Ji reached Dandi, picked up a handful of salt and broke the salt law as a symbol of the Indian People’s refusal to live under British-made laws and therefore under British rule. Gandhi Ji declared :

“The British rule in India has brought about moral, material, cultural and spiritual ruination of this great country. I regard this rule as a curse. I am ought to destroy this system of Government. … Sedition has become my religion. Ours is a non-violent battle. We are not to kill anybody but it is our dharma to see that the curse of this Government is blotted out.
