Which of the following is a type of sales promotion channel?

The correct choice identifies cooperative advertising as a type of sales promotion channel. Cooperative advertising involves a partnership between a manufacturer and a retailer to share the costs associated with advertising campaigns. This method allows both parties to promote products effectively while maximizing their budgets. By leveraging the strengths of both the manufacturer’s products and the retailer’s reach, cooperative advertising enhances brand visibility and encourages consumer engagement, ultimately driving sales.

The other options represent different marketing strategies but do not fit into the specific category of sales promotion channels. Social media advertising is a form of digital marketing aimed at promoting products through social platforms, rather than being a direct approach to sales promotions. Public relations activities focus on maintaining and managing the public perception of a brand, which is distinct from sales promotions that directly incentivize purchases. Telemarketing is a direct marketing technique where sales representatives use the phone to sell products or services, which again falls outside the realm of traditional sales promotion channels.
