To "repudiate" means to reject its validity. This verb is used to indicate a strong disavowal or denial of any association with something, often in a formal or emphatic manner. When someone repudiates a statement, belief, or claim, they are declaring it to be untrue or unfounded, effectively distancing themselves from it and refusing to accept it as valid.

The other options do not align with the meaning of "repudiate." Embracing something suggests acceptance and support, which is the opposite of rejecting it. Supporting it firmly also conveys a sense of affirmation, contrasting the intent of repudiation. Ignoring it implies a lack of attention or response, rather than an active denial of its validity. Thus, the choice that accurately represents the meaning of "repudiate" is the one about rejecting validity.
