Dear Student,

◆ Answer - (b)

Blood group AB has no antibody.

◆ ABO blood group system -

- Carl Landsteiner classified blood groups according to presence/absence of antigens A & B on RBCs.

- Group A have A antigen and B antibody.

- Group B have B antigen and A antibody.

- Group AB have both A & B antigen but no antibodies.

- Group O have no antigens but A & B antibodies.

- Blood group O is called universal donor because it dont have any antigens.

- Blood group AB is called universal acceptor because it doesn't produce any antibodies.

Thanks dear..
