The correct answer is (a) Jawahar Lal Nehru.
Jawaharlal Nehru was the first satyagrahi in the Individual Satyagraha Movement. He was selected by Mahatma Gandhi because he was a well-known and respected leader who could inspire others to join the movement. Nehru was also a skilled orator and writer, and he was able to use his talents to spread the message of satyagraha to a wide audience.
Sardar Patel was a close associate of Gandhi and a leading figure in the Indian independence movement. He was a skilled administrator and organizer, and he played a key role in the integration of the princely states into the Indian Union after independence.
Sarojini Naidu was a poet, writer, and politician who was also a close associate of Gandhi. She was a gifted orator and a passionate advocate for Indian independence.
Vinoba Bhave was a Hindu monk and social reformer who was also a close associate of Gandhi. He is best known for his work in the Bhoodan movement, which aimed to redistribute land to the landless.
All four of these individuals were important figures in the Indian independence movement, but Nehru was the first satyagrahi in the Individual Satyagraha Movement.
