Many Americans first grew aware of the life and death struggle of civil rights activists when

a. Malcolm X was murdered by a white mob in the Watts section of Los Angeles.
b. Martin Luther King Jr. published Letter from Birmingham Jail.
c. television news programs showed men, women, and children being beaten, blasted with water, and attacked by police dogs during a protest march in Birmingham, Alabama.
d. the Kerner Commission reported that “the nation is rapidly moving toward two increasingly separate Americas”—one white and wealthy, the other African American and poor.
