Answer:
The correct answer is letter "D": A magazine ad that asks you to call a toll-free number for more information.
Step-by-step explanation:
Print advertising refers to promotional publications spread to paper media such as newspapers, flyers or magazines. Some of them include a direct-response feature which is nothing more than incentivizing readers to contact the publishing store or company so the consumer can take advantage of certain benefits such as product discounts or simply to obtain more information about a good or service.
In such a way, a magazine ad asking readers to call a toll-free number for more information is an example of direct-response print advertising.
