Which Indian mass movement began with the famous 'Dandi March' of Mahatma Gandhi?
Explanation
Why Correct: The Civil Disobedience Movement began with Gandhi's Dandi March on March 12, 1930, where he walked 240 miles to Dandi to make salt in defiance of the British salt tax.
Distractor Analysis: The Khilafat Movement (1919-1924) protested the dismantling of the Ottoman Caliphate after World War I. The Non-Co-operation Movement (1920-1922) involved boycotting British institutions, schools, courts, and foreign goods. The Quit India Movement (1942) demanded immediate British withdrawal during World War II with the "Do or Die" slogan.
Takeaway: The Dandi March lasted 24 days, ending on April 6, 1930, when Gandhi broke the salt law at Dandi beach, sparking widespread salt satyagraha across India.
