Answer:
C. The booming economy had created a larger black middle class.
Explanation:
There is a long history of the struggle for civil rights by the minorities in the United States. Before the Second World War, most African Americans were low-wage farmers, factory employees, household employees or servants. But early 1940's changed the situation because the rising economy during the wartime created some opportunities for them. Secondly, Blacks fought bravely during this time. As the war ended they now demanded equal participation in American society.
