The correct answer is "A".
The "Great Migration" was the massive relocation of African Americans to territories up North, Midwest, and West which occurred from 1916 to 1970. During this period, African Americans who relocated into urban areas in the north were subject to constant violent acts from the White community, as there was still an inherent sentiment of segregation among the citizens of the country. This prompted African Americans to establish in suburbs in the outskirts of the urban areas during the 1950s.
