Correct answer: ADE
Explanation:
A Service is a means of packaging reusable software building blocks to provide functionality to users, applications, or other Services; it is an independent, self-sufficient, functional unit of work that is discoverable, manageable, measurable, has the ability to be versioned, and offers functionality that is required by a set of consumers. A Service may be shared, which means that the function offered by the Service is intended for multiple consumers, some known, and others that have not yet been identified.
