Final answer:
The concept of cultural relativism posits that ethical behavior is culturally dependent and that no single standard of ethics applies universally. It is supported by the theory of Normative Ethical Relativism which states that moral systems are correct within their own cultural context.
Step-by-step explanation:
The concept that suggests that ethical behavior is dependent on cultural context and that there is no single right way to behave universally is cultural relativism. Cultural relativism acknowledges that different societies and cultures have their own rules, customs, and moral systems, and that what is considered ethical in one culture may not be considered so in another.
This perspective reflects the understanding that moral values are not universal and cannot be judged by a single standard applicable to all people at all times.
The theory of Normative Ethical Relativism goes further by stating that each culture's moral system is correct in its own context and that no external moral principles can override a culture's dominant views, even when considering criticisms and reforms proposed by minorities within those communities.
