In legal or formal contexts, to "repudiate" can mean:

To "repudiate" in legal or formal contexts primarily means to reject or disown. This term is often used to describe the act of refusing to recognize or support a particular claim, statement, or obligation. For instance, a party may repudiate a contract if they assert that they are not bound by its terms, indicating a complete disavowal of any associated responsibilities or agreements.

The essence of repudiation lies in its definitive and formal nature; it conveys a strong unwillingness to accept or be associated with something. This distinguishes it from other responses in the choices. Accepting something with enthusiasm, revising, or negotiating terms involve different actions and sentiments that do not align with the act of outright rejection or disownment inherent in repudiation.
