Answer: B) It was one of the most segregated cities in America.
Details: In point of fact, Birmingham was known by reputation as "the most segregated city in America." In his Letter from a Birmingham Jail, Dr. Martin Luther King, Jr., said that he had come to Birmingham because injustice existed there, in the same way that Old Testament prophets had left their own towns and villages to go and confront injustice in other towns in their day.
Birmingham also became a central point of focus because of a tragedy that had occurred there. In September, 1963, the 16th Street Baptist Church in Birmingham was bombed in an act of terrorism by Ku Klux Klan members. Four black girls (ages 11-14) were killed, and and fourteen other persons at the church were injured. The bombing in Birmingham sparked the African American community into strong action in Alabama to push for the rights of black citizens.
