Which of the following would be considered an example of a product item?

A product item refers to a specific version or model of a product that is distinct and identifiable within a product line. In this context, a specific model of a smartphone represents a unique product that can be differentiated from other smartphones by its features, design, and specifications. For instance, a particular model might have a certain screen size, camera quality, or operating system, making it a tangible and distinct offering in the broader smartphone market.

The other choices do not define a product item. A category of product refers to a group of related products that share similar characteristics, but it does not point to a specific item. A brand’s target market focuses on the demographic or audience a company aims to reach, while a company’s marketing strategy outlines the plan for promoting its products and services. Neither of these options refers to a specific, individual product, which is why they do not qualify as examples of a product item. Thus, the correct answer is indeed a specific model of a smartphone.
