Answer:
C) propagating certain cultural stereotypes
Step-by-step explanation:
This is true not only for advertising but also for many mass media products. The problem is that sometimes reality is very different than the stereotypes that are portrayed.
One of the most controversial issues is the models' weight. Models tend to be usually much thinner than regular people, and that leads to a misconception that being extremely thin is good and healthy. Besides personal beauty preferences, a girl who is 5 foot 10 and weighs only 100 pounds is not healthy.
Similar issues like portraying certain family or lifestyle stereotypes may also have positive or negative effects on the audience since advertisement reaches millions of people.
