What term describes a set of moral principles that a specific group or culture agrees upon?

The correct term that describes a set of moral principles agreed upon by a specific group or culture is "ethics." Ethics encompasses the standards and principles that guide behavior and decision-making within a group, influencing how individuals interact with one another and their environment. These moral guidelines can vary greatly between different cultures, professions, and organizations, shaping what is considered right and wrong in various contexts.

Conduct refers more to actual behavior or actions rather than the underlying principles that inform those actions. While norms can describe expected behaviors or standards within a group, they do not specifically pertain to the moral principles but rather the social rules that govern behavior. Values are the beliefs and ideals that individuals or groups hold dear, but they don't necessarily imply a systematic framework of moral principles like ethics does. Thus, ethics is the most accurate term to describe a cohesive set of moral principles within a group.
