Final answer:
A relativist, adhering to normative ethical relativism, would not accept the statement that some societies have better moral codes than others, since they believe there are no objective moral standards.
Step-by-step explanation:
The question asks which statement a relativist would not accept. A relativist, according to normative ethical relativism, believes that there are no absolute universal moral standards that are binding on all people at all times and that morality differs from one society to another. Therefore, the statement a relativist would not accept is C) some societies have better moral codes than others, as this implies that there is a way to objectively compare and evaluate differing moral codes, which directly contradicts the relativist perspective.
