Answer 2

The correct answer is A. Migration of African Americans from southern farms to northern factories.

This movement is known in American history as the Great Migration. Besides the economic opportunities available in the north, African Americans also moved to the north for a greater sense of freedom. At this time, racial tensions in the south were very high. The existence of Jim Crow laws and the constant presence of the Ku Klux Klan made southern states undesirable for African American citizens.
