Explanation:

- C. Rajagopalachari, also known as Rajaji, was a prominent leader in the Indian independence movement.

- In April 1930, inspired by Mahatma Gandhi's Salt March to Dandi, Rajaji initiated a similar march in Tamil Nadu.

- The march began from Tiruchirappalli and ended at Vedaranyam.

- It was at Vedaranyam that Rajaji broke the salt law by making salt on April 30, 1930.

- Option 1: Vedaranyam is the correct location where the salt law was broken.

- Option 2: Tiruchi (Tiruchirappalli) was the starting point of the march, not the place of the salt law violation.

- Option 3: Tirupati is unrelated to this event.

- Option 4: Madurai is also not related to this particular action against the salt law.

Option 1: Vedaranyam
