The most accurate difference between the approaches of Martin Luther King Jr. and Malcolm X is:
b) King believed in civil disobedience, while Malcolm X believed violence was sometimes appropriate.
Martin Luther King Jr. advocated for nonviolent resistance and civil disobedience as a means to achieve civil rights and social justice, drawing inspiration from Mahatma Gandhi. In contrast, Malcolm X initially supported a more militant approach and believed that armed self-defense was a legitimate response to oppression. He emphasized the need for Black empowerment and was critical of the civil rights movement's strategies at times.
