Quizplus · Accepted Answer

Because his blood agglutinates with anti-A serum but not with anti-B, Bill's blood type is A. This means that his plasma contains B antibodies, as individuals in blood group A produce antibodies against the B antigen. Therefore, choice D is true. The other choices are incorrect as Bill cannot receive type B blood as his body would produce an immune response against the B antigen (choice A), cannot donate blood to an individual with type B blood as their blood would also agglutinate (choice B), his Rh factor cannot be determined from this test (choice C), and his plasma would not cross-react with type O red blood cells since type O blood lacks both A and B antigens.
