Explanation:

The U.S. Office of War Information (OWI) during wartime (e.g., WWII) used propaganda posters to encourage public support and participation in the war effort. Television was not a widespread medium for commercials during WWII, political rallies were not the primary method of the OWI, and making phone calls to the public was not a standard OWI practice.

Answer:

a. created posters
