Answer:
B Families can only use specific amounts of certain foods.
Explanation:
In the case of total wars, many people in the home front would have to try to regulate what kinds of food they are able to eat, as those may have high-concentrate in nutrients and/calories, as well as have a longer shelf-life, allowing it to be a useful food for soldiers to carry and eat while in the field. This means that to feed the troops, the supply of these food to the general public would be limited. This is especially the case of total war, where large amounts of troops need to be fed, which led to a larger demand than normal.
