Answer:
С
. Demand for labor in war industries helped increase employment
Explanation:
The poster claims that jobs people do on the homefront can claim the victory. These jobs would include the production of goods for the military, ammunition, clothes, tanks, transport, etc.
The industry during the war was in high demand as the military on the fronts demanded plenty of things, but there were still needs of people at home that had to be met. Therefore, there were many available jobs. Not only men who stayed home were well employed, but women started getting jobs in the positions vacated by men who fought in the war. This created job opportunities for many and increased the number of employed people much more than before, especially since for the first time in history so many women have been employed in various positions.
