Which work did Martin Luther King Jr. write after the Birmingham campaign to condemn segregation and injustice?

• A. March on Washington
• B. NAACP
• C. Sit-Ins
• D. Letters from Birmingham Jail

Answer: (D)

The main idea here is identifying the written work MLK produced in response to the Birmingham campaign that addresses segregation and injustice. He wrote the Letters from Birmingham Jail in 1963 while he was jailed in Birmingham after peaceful protests against segregation. In these letters, he argues why segregation is unjust, defends the use of nonviolent civil disobedience, and explains the moral responsibilities of both activists and critics. The letters became a famous defense of civil rights, stressing that injustice anywhere is a threat to justice everywhere and calling for moral action to end segregation.

That makes it the best answer because it directly fits the description of a written work created after the Birmingham protests that condemns segregation and injustice. In contrast, the March on Washington was a major protest event and included MLK’s famous “I Have a Dream” speech, not a jail letter; the NAACP is the civil rights organization with which MLK was involved, not a written work; and sit-ins were a protest tactic, not a written work.
