The correct action is B) African Americans and women.
The two groups who benefited economically from wartime production were African Americans and women.
When the United States entered the war, the Army drafted many white men. They had to leave their jobs in order to go to war. But industries had to continue with the production of supplies, weaponry and all the necessities that were needed to help the war effort. So women and black people took many jobs left by white men that enlisted in the US Armed Forces. So both groups really benefited from those job vacancies. For many women, the work in the industries represented their first work outside the home.
