Which term refers to a collection of related products offered by a single business?

The term that refers to a collection of related products offered by a single business is "Product Range." This concept encompasses the various products that are grouped together based on similarities, such as function, target market, or brand. A business's product range can include multiple items that serve a related purpose, allowing customers to choose from a variety of options within that specific category of products.

While other terms like "Product Category," "Product Portfolio," and "Product Mix" do relate to collections of products, they are used in slightly different contexts. "Product Category" typically refers to a broader classification and may include many product ranges. "Product Portfolio" usually denotes the full assortment of products offered by a business, including unrelated products. "Product Mix" is a similar concept that refers to the combination of various products a company offers, but it does not focus specifically on the related nature of those products like "Product Range" does. Therefore, "Product Range" best captures the idea of a specific set of related products offered by a business.
