Answer:
A fear appeal
Step-by-step explanation:
In advertising, a fear appeal uses consumers fear to motivate them to purchase a product or contribute to a cause. The consumer appraises the product in light of their fear of the consequences of not buying. For example, an ad compaign may appeal to people's fear of body odor to convince them to buy deodorant.
Hence a fear appeal is the type of appeal used to suggest to the consumer that he or she can avoid some negative experience through the purchase and use of a product or service, a change in behaviour or a reduction in the use of a product.
