Which term refers to the principles of right action that guide acceptable behavior within a group?

The correct answer is the term "Ethics." Ethics refers to the principles of right action that guide acceptable behavior within a group. This concept encompasses the moral standards and guidelines that inform how individuals within a community interact, make decisions, and conduct themselves. In a professional or organizational context, ethics shape what is considered acceptable conduct among members, defining a collective understanding of right and wrong.

Norms typically describe the unwritten rules and expectations that influence behavior in specific contexts, but they may not explicitly address the moral implications of actions. Values are more about individual beliefs and priorities, which can vary greatly from person to person. Protocols refer to formal guidelines or procedures to be followed, often in specific situations, without necessarily addressing the underlying ethical considerations. Therefore, "Ethics" serves as the overarching principle that informs both norms and values within a group setting.
