Photo A is a credible source because it seems to lack ulterior motive, by providing relevant knowledge regrading one’s health. It provides a catchy way to grain one’s attention concerning the seriousness of a healthy diet.

Photo B is a non-credible source because the communicator, Kylie Jenner, has personal stake in the product that she is advertising. She, among other celebrities that promote the weight loss tea , do not actually use them or need to use them. However, they promote the product because they are paid to do so regardless of the products actualities.

Photo C is an attractive source because it is appealing and likable by many. This source can be found effective because it drives burger lovers to want to purchase Burger King’s special charbroiled burgers. Although the ad may not mirror the real burger, the presentation the ad provides, draws consumers to try it.
