Which term refers to a set of moral principles; a theory or system of moral values?

• A. Advocate
• B. Ethics
• C. Autonomy
• D. Macrosystem

Answer: (B)

The concept being tested is the idea of a system that defines right and wrong and guides behavior. Ethics is the term that names a set of moral principles or a theory or system of moral values. It covers how we reason about what ought to be done and the standards used to judge actions, both in everyday life and in professional settings like healthcare, where codes of ethics shape decisions.

Advocate describes a person who promotes or supports a cause, which isn’t a system of values. Autonomy refers to the capacity to govern oneself and make independent choices, a principle within ethics but not the overall system. Macrosystem points to broad social, cultural, or environmental contexts, not to moral principles themselves.

So, ethics is the best fit because it directly names the organized framework of moral values used to evaluate actions.
