Kyan · Answer 1

The answer is A. Only anti-A antibodies are present. The ABO blood classification is based on the presence or absence of the antigens on the surface of the red blood cells. Individuals with blood group B have the B antigen on the surface of the red blood cells. Thus, they do not have anti-B antibodies but they have only anti-A antibodies.
