The promotional concept that describes the set of promotional tools used to communicate with customers.

• A. Direct mail
• B. Publicity
• C. Promotional mix
• D. Word of mouth

Answer: (C)

The concept being tested is the promotional mix—the set of promotional tools a company uses to communicate with customers. It refers to how a business chooses and coordinates different methods to inform, persuade, and remind customers about its products or services. The promotional mix can include advertising, personal selling, sales promotions, public relations, direct marketing, and digital channels. Direct mail is just one possible tool within that mix, publicity is a form of public relations, and word of mouth is another informal method. Because the question asks for the overall set of tools used to communicate, the term that fits best is the promotional mix.
