What type of advertisement typically focuses on showcasing the benefits of a specific product?

The correct answer is product advertising because this type of advertisement is specifically designed to highlight the features, advantages, and overall benefits of a particular product. The primary goal of product advertising is to persuade consumers to purchase the product by demonstrating its value and how it meets the needs or desires of potential buyers.

In contrast, institutional advertising primarily aims to promote a company or organization as a whole rather than a specific product, focusing on its brand image or ideals. Comparative advertising involves directly comparing one product to another to show superiority, which could lead to a focus on both products instead of solely on the benefits of one. Public service advertising aims to inform or educate the public about social issues or initiatives rather than to promote a commercial product. Thus, the emphasis of product advertising on individual offerings makes it the correct choice for this question.
