(B) The correct answer is $B$. Parents are heterozygous for blood groups $A$ and $B$,meaning their genotypes are $I^A i$ and $I^B i$. When these parents cross,the possible combinations of alleles in the offspring are: $1. I^A I^B$ (Blood group $AB$) $2. I^A i$ (Blood group $A$) $3. I^B i$ (Blood group $B$) $4. ii$ (Blood group $O$) Therefore,the children can have any of the four blood groups: $A, B, AB,$ or $O$.
