(D) The inheritance of $ABO$ blood groups is controlled by the gene $I$. The gene $I$ has three alleles: $I^A$,$I^B$,and $i$.If the mother has blood group $B$,her genotype can be $I^B I^B$ or $I^B i$.If the father has blood group $A$,his genotype can be $I^A I^A$ or $I^A i$.Considering the heterozygous condition ($I^B i$ and $I^A i$),the cross is $I^A i 	imes I^B i$.The possible genotypes of the offspring are $I^A I^B$ $(AB)$,$I^A i$ $(A)$,$I^B i$ $(B)$,and $ii$ $(O)$.Therefore,all four blood groups $(A, B, AB, O)$ are possible in the offspring.

If the mother's blood group is $B$ and the father's is $A$,what blood group$(s)$ can their offspring have?
