Which of the following is a paid form of communication about a product or service?

Advertising is indeed a paid form of communication about a product or service. It is designed to reach a wide audience with the intention of informing or persuading them to purchase a product, use a service, or engage with a brand. Advertisers pay for the placement of their messages in various media channels, such as television, radio, online platforms, and print, which differentiates it from other forms of communication that may not involve a financial exchange.

Public relations, on the other hand, focuses on managing the public image and building relationships between the organization and its stakeholders without direct payment for media coverage. Promotion can sometimes involve paid elements, like discounts or special offers, but it typically refers to a broader set of activities aimed at increasing awareness rather than direct advertising. Sales strategy encompasses the methods and plans that businesses use to sell their products or services, which may include both paid and unpaid approaches but is not limited to communication alone.
