The correct option is B South Africa
Mahatma Gandhi arrived in India in 1915 from South Africa.
Having led Indians in that country in non-violent marches against racist restrictions, he was already a respected leader, known internationally. His South African campaigns had brought him in contact with various types of Indians: Hindus, Muslims, Parsis and Christians; Gujaratis, Tamils and north Indians; and upper-class merchants, lawyers and workers.
