AO is the answer because type O blood is recessive and that parent must have OO  as their genotype to that type O blood as a phenotype thereby excluding the possibility of the type O parent from giving their offspring anything but type O allele so if one parent gave the child type A and the other parent gave the child type O then the child will be AO genotype but their phenotype will be type A.
