Answer:
D. The patient's B antigens (antiglutinogens) will agglutinate with the anti-B antibodies (agglutinins) in the donor blood.
In the ABO blood group system, individuals with type B blood have B antigens on the surface of their red blood cells and produce anti-A antibodies in their plasma. When they receive a transfusion of AB blood, which contains both A and B antigens, their anti-A antibodies will not react with the A antigens in the donor blood. However, their B antigens will agglutinate with the anti-B antibodies in the donor blood, leading to a transfusion reaction.
