What defines a feature in the context of a product or service?

In the context of a product or service, a feature is best defined as a characteristic that remains consistent regardless of purchase. This means that a feature is an inherent aspect of the product or service that can be consistently identified and described, regardless of who the customer is or when the product is purchased. For example, if a car model has a specific type of engine or safety feature, those characteristics are part of the car's design and remain the same for every unit sold.

This consistent nature of features differentiates them from other terms such as benefits or unique selling propositions, which may vary based on individual customer perspective or market strategy. While a unique selling proposition emphasizes what makes a product stand out in the marketplace, and benefits describe why those features matter to the consumer, features themselves remain factual and constant representations of the product or service being offered. Therefore, option B accurately captures the essence of what constitutes a feature.
