Which of the following traits describes the 'width' of a product mix?

The 'width' of a product mix refers specifically to the number of different product lines that a company offers. Each product line represents a distinct category of products intended for similar functions or target markets, helping to convey the overall scope of the company's offerings. By assessing the width of the product mix, businesses can evaluate the diversity of their products and how broadly they cater to different consumer needs.

In contrast, other traits mentioned in the options focus on different aspects of the product mix. The total number of products offered pertains to the overall depth and breadth of products, while the number of variations within a product line relates to the diversity of items within a single category rather than across multiple lines. Lastly, the relatedness of product lines addresses how closely aligned different product lines are, rather than the count of those lines themselves. Understanding these distinctions is crucial for marketers when developing strategies for product differentiation and market positioning.
