What does the term "repudiate" mean?

The term "repudiate" means to cast off or disown, which is why option B is correct. In a practical context, when someone repudiates a belief, an idea, or even a relationship, they are effectively rejecting or disavowing it. This action conveys a definitive stance against something that they no longer want to be associated with or recognize.

In contrast, options that suggest support, acceptance, or restriction do not align with the meaning of "repudiate." Support or endorsement would imply agreement and acceptance, whereas to accept or acknowledge signifies recognition of something, which is the opposite of repudiating it. Confine or restrict denotes a sense of limitation rather than disowning or rejecting, further indicating that these alternatives do not capture the essence of the word "repudiate."
