Blood groups have been named according to the presence of antigens on the surface of RBC. A person with blood group A will have antigen A and anti- b antibodies. A person with blood group B will have antigen B and anti- A antibodies. A person with blood group AB carries both antigens A and B and none antibodies. A person with blood group O carries none of the antigens but has both anti- A and anti- B antibodies. Thus, the correct answer is option B.
