The best synonym for "repudiate" is "reject." To repudiate something means to refuse to accept or be associated with it. This word often conveys a sense of denial or disavowal, indicating that the speaker distances themselves from a particular idea, belief, or claim. In this context, "reject" aligns perfectly because it also implies a refusal to accept or endorse something.

On the other hand, "support," "agree," and "define" convey positive actions of acceptance or endorsement, which directly contradict the meaning of "repudiate." Therefore, "reject" stands out as the most appropriate synonym.
