The correct answer is option 1, Gandhi. Gandhi, also known as Mahatma Gandhi, is credited with coining the term `Satyagraha`. Satyagraha is a Sanskrit word that combines `Satya`, meaning truth, and `Agraha`, meaning insistence or holding firmly. It is a philosophy and practice of nonviolent resistance and civil disobedience, which Gandhi used as a central strategy in India`s struggle for independence from British rule. He believed in the power of truth and nonviolence to bring about social and political change, and he used Satyagraha as a means to mobilize the Indian people against injustice and oppression. Through peaceful protests, boycotts, and acts of civil disobedience, Gandhi sought to establish a just and equitable society.
