Answer:
B) to make certain there were enough raw materials for war production.
Step-by-step explanation:
The US entered World War II after the bombing of the US military base Pearl Harbor in Hawaii. In order to have success, the government developed a rationing policy to ensure that there were enough goods for the war effort. The US government used propaganda and advertisements to encourage reduced consumption by citizens at home as well. This helped in ensuring US victory in World War II.
