The correct answer is C. The Younger deciding to move to Clybourne Park.
At this point of the play "A Raisin in the Sun", by Lorraine Hansberry, the Younger decide to abandon Southside Chicago, their neighbourhood asociated with working-class African Americans. Many Blacks arrived in Chicago and other cities in the North emigrating from the South, looking for better jobs and escaping racism.
Still, white society, as reflected in the play, intended to keep Blacks in segregated neighborhoods, in the cramped houses of Southside Chicago. The Younger inherited life insurance from the late father, and they decide to move to Clybourne Park, a white neighborhood in order to improve their living conditions, but once again, they will be harassed to sell their house and leave the white neighborhood.
Thus, the play reflects on racism and the topic of neighborhood integration, a debate initiated by African Americans like the Younger, risking their safety when they moved to white neighborhoods.
