As per ABO blood grouping system, the blood group of father is $\displaystyle \mathrm{B}^{+}$, mother is $\displaystyle \mathrm{A}^{+}$and child is $\displaystyle \mathrm{O}^{+}$. Their respective genotype can be A. $\displaystyle \mathrm{I}^{\mathrm{B}} \mathrm{i} / \mathrm{I}^{\mathrm{A}} \mathrm{i} / \mathrm{ii}$ B. $\displaystyle \mathrm{I}^{\mathrm{B}} \mathrm{I}^{\mathrm{B}} / \mathrm{I}^{\mathrm{A}} \mathrm{I}^{\mathrm{A}} /$ ii C. $\displaystyle \mathrm{I}^{\mathrm{A}} \mathrm{I}^{\mathrm{B}} / \mathrm{iI}^{\mathrm{A}} / \mathrm{I}^{\mathrm{B}} \mathrm{i}$ D. $\displaystyle \mathrm{I}^{\mathrm{A}} \mathrm{i} / \mathrm{I}^{\mathrm{B}} \mathrm{i} / \mathrm{I}^{\mathrm{A}} \mathrm{i}$ E. $\displaystyle \mathrm{iI}^{\mathrm{B}} / \mathrm{iI}^{\mathrm{A}} / \mathrm{I}^{\mathrm{A}} \mathrm{I}^{\mathrm{B}}$ Choose the most appropriate answer from the options given below :
