Martin Luther King, Jr. and Malcolm X were both important figures in the American civil rights movement. Which of the following statements BEST describes a difference between their respective approaches to civil rights?

While Martin Luther King is famous for his advocacy of nonviolence, Malcolm X defended self-defense against aggression by white people. In the course of his work, King did indeed mobilize ordinary citizens; however, Malcolm X did not focus on working with local white political leaders, but instead focused on black communities. Malcolm X also sometimes spoke against black citizens practicing Christianity, linking the practice of that religion in part to oppression. Finally, "Martin Luther King, Jr. related Christianity to civil rights..." can be rejected because King did not promote Black Nationalism, while Malcolm X did.
