The correct answer is C.
Mohandas Gandhi was an Indian activist who was the leader of the Indian independence movement against the British colonial rule.
He became famous for employing his nonviolent civil disobedience to achieve his political goals. It is a practice of being harmless to self and others under every condition. Abstention of violence means that hurting people and animals is unnecessary and other ways of resolving conflicts should be found.
Some followers of this practice of nonviolent approach were Nelson Mandela in South Africa and Martin Luther King Jr. in the United States.
