The Dandi March is associated with the Civil Disobedience Movement, thus making option 3 the correct answer. Let`s briefly understand each of the options to cement this understanding:

1. Home Rule Movement – This was an Indian political movement that aimed for self-government during the British Raj, and was active between 1916-1922, long before the Dandi March which occurred in 1930.

2. Non-Cooperation Movement – Led by Mahatma Gandhi, it aimed to resist British rule in India through non-violent means. It began in 1920, almost a decade before the Dandi March.

3. Civil Disobedience Movement – This movement initiated with the Dandi March that took place in 1930, where Mahatma Gandhi along with his followers, marched to the Arabian Sea to make salt, thereby breaking the Salt Law imposed by the British.

4. Quit India Movement – This was a civil disobedience movement launched in India in August 1942 in response to Gandhi`s call for immediate independence. Again, this occurred much later than the Dandi March.

Therefore, Dandi March, an act of nonviolent civil disobedience, marked the start of the Civil Disobedience Movement making the third option the correct
