The correct answer is: a) Rajaji (C. Rajagopalachari).
Rajaji (C. Rajagopalachari) was a prominent Indian independence activist, statesman, and writer. He was the first Indian Governor-General of India, and the second Chief Minister of Madras Presidency. He was also a close associate of Mahatma Gandhi, and played a key role in the Salt Satyagraha of 1930.
The Salt Satyagraha was a major nonviolent protest against the British salt monopoly in India. It was launched by Mahatma Gandhi on March 12, 1930, and lasted for 24 days. The protest was successful in drawing attention to the British salt monopoly, and it helped to galvanize support for the Indian independence movement.
Rajaji played a key role in the Salt Satyagraha in Tamil Nadu. He led a significant march from Tiruchirappalli to Vedaranyam, where he broke the salt law by making salt from seawater. His actions inspired many others to join the protest, and the Salt Satyagraha became a major turning point in the Indian independence movement.
