(C) The genotype for blood group '$A$' can be $I^AI^A$ or $I^Ai$,and for blood group '$B$' can be $I^BI^B$ or $I^Bi$.If the father is $I^Ai$ (heterozygous) and the mother is $I^BI^B$ (homozygous),the offspring will have $I^AI^B$ ($AB$ blood group) and $I^Bi$ ($B$ blood group),resulting in a $50\%$ probability of $AB$ blood group.Similarly,if the father is $I^AI^A$ (homozygous) and the mother is $I^Bi$ (heterozygous),the offspring will have $I^AI^B$ ($AB$ blood group) and $I^Ai$ ($A$ blood group),which also results in a $50\%$ probability of $AB$ blood group.Therefore,a $50\%$ probability of $AB$ blood group is obtained only when one of the parents is heterozygous and the other is homozygous.

In a family,the father has blood group '$A$' and the mother has blood group '$B$'. If the probability of their offspring having blood group '$AB$' is $50\%$,this indicates that:
