Answer:
A family farm.
Step-by-step explanation:
During World War II, the domestic scenario within the American territory was called "home front", where families and all those individuals who were not in the combat zone, both in Europe and in the Pacific, were morally obliged to contribute to the war effort, both through the labor effort in the production of armaments, supplies and food for the military in battle, as well as through the saving of own resources to generate surpluses that contribute with said resources destined to the armed forces.
Thus, family farms, which generated food for each family group, thus saving productive effort for it to be destined for the armed forces, were an essential part of the home front during the war.
