The option that is the best example of propaganda is A, a picture of a popular movie star shaking hands with the president. This is so because the definition of propaganda refers to a message designed to persuade its intended audience to act or to think in a particular way. If you show a movie star shaking hands with the president, you are telling the audience that that person supports him/her. Therefore, many people may think that if that movie star likes the president then he/she must be doing something good and start supporting them themselves.
