Which of the following is a confidential question?

From the Promotions Topic Lesson, it seems like some tactics can be classified as more than one promotional mix element. For example, a social media click$-$through ad that gives the consumer $10\%$ off their purchase has elements of both advertising and sales promotion. Is that correct?

For the Promotions Quiz question, "A coupon is an example of which promotional mix element?" I chose "Advertising," because coupons advertise that you can buy a product for a lower price. I read the question feedback and rewatched the topic lesson, but I still don't understand why my answer is incorrect. Can you help me understand?
