Which term refers to a group of closely related products within the product mix?

The term that refers to a group of closely related products within the product mix is a product line. A product line consists of products that fall under a similar category or are related by function, branding, price range, or target market. For example, a cosmetic company might offer a product line solely focused on skincare, which includes moisturizers, cleansers, and serums.

This grouping allows for targeted marketing strategies and can create synergy among the products, as they can benefit from each other’s marketing efforts. The concept of a product line emphasizes the connection between the products, making it easier for consumers to understand the brand's offerings and for marketers to position them effectively in the marketplace.
