Answer :
The persuasive technique being used in the advertisement Corey is analyzing is C. Bandwagon.
The bandwagon technique is a persuasive method that encourages individuals to do something because it claims that the majority of people are doing it. The idea is that one should 'jump on the bandwagon' to not be left out or seem different from the majority.
In this case, the advertisement is suggesting that most people use sunscreen, implying that it's a popular or common behavior. This can persuade others to follow suit and use sunscreen as well, simply because many others are supposedly doing it.
Using the bandwagon appeal aims to create a sense of social pressure, making potential consumers feel they need to conform to what everyone else is doing to fit in or be part of a trend. This technique is common in marketing to increase the adoption of a product or idea.
The bandwagon technique aims to persuade the audience to join or follow the majority. By indicating that the majority of the population uses a specific brand of sunscreen, the advertisement is suggesting that the student should also use the same brand in order to be part of the majority.
