The correct answer is A) rationing consumer goods such as food and gas.
While World War II raged outside of the United States, attempts were made in the U.S. to support the war effort by rationing consumer goods such as food and gas.
The federal government was committed to sent food, weapons, and all kind of supplies to the war front. So it asked its citizens to ration food and gas. Indeed, that is when the victory gardens became a good idea. The government asked people to plant victory gardens in their backyard to grow vegetables and fruits.
