What does "repudiate" mean?

"Repudiate" means to reject or refuse to accept something, particularly in relation to ideas, beliefs, or claims that one considers to be untrue, unjust, or unfounded. This term conveys a strong dismissal or disavowal, indicating that the speaker does not endorse what is being discussed.

In this context, the correct choice emphasizes the act of rejecting, which aligns with the essence of "repudiate." It encapsulates the idea of not only disagreeing with something but also actively denouncing or renouncing its validity.

The other options involve concepts that do not capture the full meaning of "repudiate." Accepting as true implies an affirmation of the claim, which is contrary to rejection. Supporting an idea directly opposes the notion of repudiation, as it involves endorsing and promoting a belief rather than dismissing it. Ignoring a claim suggests a lack of response or acknowledgement, which, while sometimes similar, does not inherently convey the notion of rejection or disapproval that "repudiate" does.
