A) In most cases, ABO incompatibility is limited to type A mothers with a type B or O fetus.
B) Group A infants, because they have no antigenic sites on the red blood cells (RBCs) , are never affected regardless of the mother's blood type.
C) In most cases, ABO incompatibility is limited to type O mothers with a type A or B fetus.
D) ABO incompatibility occurs as a result of the fetal serum antibodies present and interaction between the antigen sites on the maternal RBCs.
