The correct answer is C) the creation of a special committee to promote the war effort.
During World War I, the US federal government created an agency aimed at promoting the war effort. This campaign consisted of a significant amount of propaganda in the form of posters. These posters encouraged citizens to ration their foods so that soldiers would be able to eat, create victory gardens so that they rely less on businesses and farms for food, and buying war bonds in order to support the government financially during this time. This type of propaganda was highly effective during this era.
