The correct answer to this question would be b. Although it is also true that African Americans were trying to move away from the terribly bad treatment they were receiving in the South due to their race, and they were discriminated and mistreated because of the color of their skin, what motivated the movement from South to North was primarily the fact that African Americans were facing economic and financial hardship because of the lack of labor opportunities. In fact, African Americans suffered great discrimination and the area of their lives that was most affected was the economic and financial area. They were forced into menial jobs that had very little economic return and they were never allowed to climb into better positions or seek better opportunities. This forced a massive movement that was given the name of the Great Migration.
