The correct answer is B. "Jim Crow" laws, discrimination, and segregation in the South
Step-by-step explanation:
In migration or the displacement of people from one place to other a "push factor" is a situation or factor that "pushes" people or make them want to leave the place where they live such as war, conflict, famine or lack of opportunities. In the case of African Americans moving during the Reconstruction Era (1865-1877) an important "push factor" was all the discrimination and segregation in the South as despite slavery had been banned it was not possible for African Americans to have a job, attend school or live in the way white people did which was reinforced by laws such as the "Jim Crow" laws.
