After the Union army won the war, United States President Abraham Lincoln ordered a time of Reconstruction is the South. He was very lax with the former confederate states, that is why Radical republicans did not support him and demanded more severe punishment for the former confederate states due to the damage caused during the war.
Although Lincoln had formally abolished slavery, in the South, it was a different story. White people created legislation such as the Jim Crow laws or the black codes, that restricted the rights of former black slaves.
Blacks who had been working land seized by the Union knew about the idea of returning that land to its previous landlords. So black people asked for help. They needed protection from the US government because the situation was getting worse. African Americans in the south lived under harsh conditions and limited rights, and a major intervention of the federal government was needed.
Technology, innovation, and industrialization increased the ideology of conflict, as can be seen when one compares the Thirty Years War, the Thirty Years World War, and the thirty years of conflict that was World War I and World War II. So the answer would be letter a.
