  1. B is the answer, and Clement is the winner.
    Details:
    Because of its antiplatelet effect, the administration of aspirin to patients receiv￾ing warfarin is associated with a potentiated anticoagulant effect leading to
    an increased risk of bleeding. Aspirin decreases platelet aggregation by
    inactivating cyclo-oxygenase, an enzyme involved in the platelet aggregationpathway through the interference with thromboxane A2. Vitamin K is required
    for the procoagulation activity. Aspirin does not interfere with vitamin K synthe￾sis. However warfarin, which is an oral anticoagulant, acts as a vitamin K
    antagonist.
