Correct Answer: Social media advertising

Solution : The correct answer is (c) Social media advertising.

Social media advertising is an example of below-the-line promotion rather than above-the-line promotion. Below-the-line promotion refers to targeted and direct marketing activities that reach specific audiences. Social media advertising falls under this category as it allows companies to target their advertisements based on specific demographics, interests, and behaviors of users on social media platforms.

Above-the-line promotion refers to mass media advertising that aims to reach a wide audience through traditional channels such as television, radio, print media, and outdoor advertising. Examples of above-the-line promotion include television commercials, radio ads, and print advertisements in newspapers or magazines.
