Explanations:Mahatma Gandhi, a pivotal figure in the Indian independence movement, spent a significant portion of his life in South Africa, where he developed his philosophy of non-violent resistance, known as Satyagraha. This period in South Africa was crucial for Gandhi's development as a leader and activist. In 1893, Gandhi moved to South Africa to work as a legal advisor for a Muslim Indian merchant. During his stay, he witnessed the racial discrimination and injustice faced by Indians and other non-white communities. This experience deeply affected him and motivated him to fight for civil rights.
Gandhi's activism in South Africa included organizing protests against discriminatory laws, such as the Asiatic Registration Act, which required Indians to register and carry identification cards. He also founded the Natal Indian Congress to fight for the rights of Indians in South Africa. Through his efforts, Gandhi gained significant experience in organizing and leading non-violent protests, which he later applied to the Indian independence movement.
While other Indian freedom fighters like Sardar Vallabhbhai Patel, Bipin Chandra Pal, and Sarojini Naidu were also instrumental in the Indian independence movement, their primary contributions were within India. They did not have significant involvement in civil rights activism in South Africa. Therefore, the correct answer is Mahatma Gandhi, as he was the only one among the options who was both a freedom fighter and a civil rights activist in South Africa.
