Answer:
B. Testimonial
Step-by-step explanation:
Testimonial advertising is employed when a famous person who has used the product, recommends it to others. Celebrities, athletes, and other popular figures are known to use quality items. So, when consumers see them wearing or using certain products, they get the belief that they are of high quality and they will be moved to also buy them.
Therefore, Lebron James, a famous basketball player, wearing a certain brand of shoes is using the testimonial advertising technique.
