Which of the following is an example of a product item?

A product item is a specific version of a product that can be offered as a standalone unit for sale. In this context, cheeseburgers are a specific type of food that can be distinctly identified and sold, making them a product item. They represent a particular offering within a restaurant's menu, characterized by specific ingredients, cooking methods, and brand identity.

In contrast, men's apparel, assortments of frozen foods, and health and beauty aids represent broader categories rather than specific items. Men's apparel might include various items like shirts, pants, and jackets, but it lacks the specificity of a single product item. An assortment of frozen foods contains multiple individual products; thus, it is not a singular item. Similarly, health and beauty aids encompass a range of products like shampoos, lotions, and cosmetics, which again are not specific items on their own.

Therefore, cheeseburgers serve as a clear example of a product item due to their singular nature within the quick-serve restaurant context.
