A) Yes: the recipient must receive blood of the same type as his or her own.
B) Yes: the anti-A antibodies of the recipient will clump and hemolyze the donated blood.
C) Yes: the recipient has anti-Rh antibodies which will clump and hemolyze the donated blood.
D) No: the recipient has no antibodies to the Rh factor because this is his first transfusion.
