Verified by Experts

The correct Answer is:
C
(c) ABO system is one of the most important human "blood group systems . The system is based on the presence or absence of antigens A and B on the surface of red blood cells and antibodies against these in blood serum . A person whose blood contains either or both of these antibodies cannot receive a transfusion of blood containing the corresponding antigens as this would cause the red cells to clump.
