What BEST describes the concept of utility ?

The correct answer is B. ITIL Version 5 defines utility as the functionality offered by a product or service to meet a particular need. Utility can be summarized as “what the service does” and is used to determine whether a service is fit for purpose. A service has utility when it supports the performance of the consumer, removes constraints from the consumer, or does both. For example, a booking application has utility if it allows customers to search for vehicles, make reservations, manage payments, and complete their journey effectively. Option A is incorrect because “fit for use” is linked to warranty, not utility. Option C is also warranty, because warranty is the assurance that a product or service will meet agreed requirements, such as availability, capacity, security, and continuity. Option D describes experience, especially user or customer experience, which concerns functional and emotional interactions with the service and provider as perceived by the stakeholder.
