Answer: (B)

Offsprings with A, B and AB blood groups

• In ABO blood group system, the classification of human blood is based on the presence or absence of the antigens A and B on the surface of the red cells. An individual may have type A, type B, type O or type AB blood.
• If parents are having blood group AB (i${}^A$ i${}^B$), then children would have blood groups AB (i${}^A$ i${}^B$), A (i${}^A$ i${}^A$) and B (i${}^B$ i${}^B$).

Thus, the correct answer is option B.
