Concept:
- The place can be reasoned out rather than merely recalled, because the act itself decides what kind of place it had to be.
- Salt can only be made where sea water is available, so the answer must be a coastal spot.
Step 1: Work out what kind of place was needed.
Breaking the salt law meant making salt without paying the tax. That is possible only at the sea shore, where sea water can be boiled or evaporated. So the place had to be on the coast.
Step 2: Work out which coast.
The march started from the Sabarmati ashram near Ahmedabad in Gujarat, and the volunteers walked on foot. The destination therefore had to be a coastal point of Gujarat within walking distance.
Step 3: Name the village.
That village was
Dandi, about 240 miles from Sabarmati. The party covered the distance in twenty four days, walking roughly ten miles a day, and reached it on 6 April 1930.
Step 4: Note why the choice was effective.
Salt was consumed by every household, rich and poor, so a tax on it touched everyone. Breaking that particular law at Dandi gave the movement a symbol the whole country could understand.
Final Answer: The salt law was broken at Dandi in Gujarat.
