The correct answer is letter D
With the abolition of slavery, the defense of these policies was intensified by some groups, such as the secret society Ku Klux Klan, formed in 1865.
One of the main events that symbolize this resistance dates back to 1955, when Rosa Parks, a member of the NACCP, when taking a bus in Alabama did not give way to a white passenger when the vehicle was overbooked. Although she was seated in a row allowed for blacks, the law required them to give up their seat to whites when the vehicle filled up.
Parks was arrested. Released after paying bail, she joined Martin Luther King, pastor and leader of black civil rights movements in the United States and a boycott against the bus system organized a few days after Parks. The boycott remained for more than a year, and in 1956, the US Supreme Court declared racial segregation in public transport unconstitutional.
