Answer: adheres to and enforces a shared ethical code among its members.

A profession is defined by its members' commitment to a specialized body of knowledge and skills, as well as their adherence to a common code of ethics. This distinguishes it from mere occupations. While service to others is a hallmark of professions, the primary focus is not on the interests of its members but on ethical standards and specialized expertise. Thus, option B is correct, as it accurately reflects the role of a code of ethics in defining a profession.
