Answer:

on the surface of RBCs., antigens are present.

A blood group has H-antigen + NAG

B blood group has H antigen and galactose

AB has H antigen and N-acetyl galactosamine + Galactose

suppose somebody got covid....then what does it's body produce antibodies right??

similarly when the blood transfusion occurs, as O has no antigen so it would produce the antibodies otherwise those A, B, AB blood group would destroy the RBCs of the person having the O blood group.
