I would say your answer is A. B wouldn't be feasible due to the South and their bias towards African Americans, C is also incorrect, because they had no choice but to join after the war, and D while accurate doesn't describe the whole picture.
The correct answer is A) They passed Black Codes to restrict the rights of black people.
The reaction of many Southern states to civil rights laws passed by Congress was that they passed Black Codes to restrict the rights of black people.
Although after the Civil War the Union had given African Americans freedom from slavery, the Southern states did not agree with the decision and decide to pass the Black Code. These great laws in the south that limited the freedom of black people. For instance, Africam Americans in the south were forced to sign labor contracts under the penalty of being arrested or fined if they did not.
