An individual in the AB blood group is a universal recipient for blood donation because
all the red blood cells do not carry antigen
all the red blood cells carry antigen
all the red blood cells carry antigen
there are no anti-A and anti-B antibodies in the serum
Vysvětlení
People with type AB blood are universal recipients because they don't have antibodies to A or B antigens, so they won't reject blood from any other blood type. They have both A and B antigens, so they don't produce antibodies to those antigens.
