Answer:
A. African Americans were strong supporters of the war effort.
Explanation:
African Americans fought in all the fronts of the Second World War, in the Army, in the Navy and in the Air Force. Many of them were brave heroes and got condecorations.
At home, thousands of African Americans moved from the countryside, towns and small cities to large cities and joined the industrial workforce of industries producing for the war effort. So, the hope of Civil Rights movements was that the positive contribution of black people to the defense of the country would help their cause.
Another 20 years had to pass before real, formal equality was achieved.
