(B) The genotypes of the parents are $I^A I^B$ (husband) and $I^A I^O$ (wife).To find the possible genotypes of the offspring,we perform a Punnett square cross:- $I^A$ from father $	imes$ $I^A$ from mother $ightarrow$ $I^A I^A$ (Blood type $A$)- $I^A$ from father $	imes$ $I^O$ from mother $ightarrow$ $I^A I^O$ (Blood type $A$)- $I^B$ from father $	imes$ $I^A$ from mother $ightarrow$ $I^A I^B$ (Blood type $AB$)- $I^B$ from father $	imes$ $I^O$ from mother $ightarrow$ $I^B I^O$ (Blood type $B$)Possible genotypes: $I^A I^A, I^A I^O, I^A I^B, I^B I^O$ (Total $4$ genotypes).Possible phenotypes: Blood type $A$,Blood type $AB$,Blood type $B$ (Total $3$ phenotypes).Therefore,the correct answer is $4$ genotypes and $3$ phenotypes.
