What does Testimonials approach rely on?

• A. Uses celebrities to talk about a product.
• B. Informs with scientific data.
• C. Documents durability through testing.
• D. Offers money-back guarantees.

Answer: (A)

Testimonial advertising relies on personal endorsements. When a celebrity or a real user talks about a product, people tend to trust the message because they recognize the person and relate to their experience. This approach uses social proof and aspirational influence to persuade, rather than presenting scientific data, durability testing results, or guarantees. So using celebrities to discuss a product captures how testimonials work.
