A Product Line consists of what?

A product line refers to a group of related products that serve a similar function or satisfy a similar need for consumers. This classification is important in marketing because it helps businesses streamline their offerings, target specific market segments more effectively, and capitalize on brand recognition across those products.

The defining characteristic of a product line is that the items within it typically vary in some attributes—like size, flavor, or features—yet they share a core function that links them together. This allows for consumer choice within a cohesive brand strategy while focusing on meeting specific customer needs.

While the other options mention aspects related to branding and pricing, they do not accurately capture the essence of what constitutes a product line in marketing. Thus, option B highlights the fundamental concept that a product line consists of a group of items that function in similar ways.
