Promotional material delivered directly to consumers' homes or workplaces.

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

Answer: (D)

Direct marketing targets individuals with promotional messages sent through a chosen channel. When promotional material is delivered directly to consumers' homes or workplaces, it is typically direct mail—printed materials like letters, brochures, or catalogs sent through the postal system. This method is controlled by the marketer, can be personalized, and allows tracking of responses, which is not the case with the other options. Advertising is a broader activity across media channels for mass audiences; publicity refers to unpaid media coverage; and word of mouth is informal recommendations between people rather than materials sent by the company.
