As per ABO blood grouping system, the blood group of father is $\mathrm{B}^{+}$, mother is $\mathrm{A}^{+}$and child is $\mathrm{O}^{+}$. Their respective genotype can be
A. $\quad{ }^{\mathrm{B}} / / \|^{A^A} / / i \mathrm{i}$
B. $\left.\quad I^{\mathrm{B}}\right|^{\mathrm{B}} /\left.\left.\right|^{\mathrm{A}}\right|^{\mathrm{A}} / \mathrm{ii}$
C. $|\mathrm{A}| \mathrm{B} /\left.i\right|^{\mathrm{A}} /\left.\right|^{\mathrm{B}} \mathrm{j}$
D. $\quad \mathrm{A}_{\mathrm{A}} / I^{\mathrm{B}} / /^{\mathrm{A}} \mathrm{i}$
E. $\quad \mathrm{il}^{\mathrm{B}} /\left.\mathrm{i}\right|^{\mathrm{A}} /\left.\mathrm{I}^{\mathrm{A}}\right|^{\mathrm{B}}$

The correct answer is:
A only
Genotype of father with blood group $\mathrm{B}^{+}=І^{\mathrm{B}} / / \mathrm{i}^{\mathrm{B}}$
Genotype of mother with blood group $\mathrm{A}^{+}=\mid \mathrm{A}_{\mathrm{A} /\left.\right|^{\mathrm{A}}}$
Genotype of child with blood group $\mathrm{O}^{+}=\mathrm{ii}$
Hence only ' $A$ ' is correct.
Genotype of mother with blood group $\mathrm{A}^{+}=\mid \mathrm{A}_{\mathrm{A} /\left.\right|^{\mathrm{A}}}$
Genotype of child with blood group $\mathrm{O}^{+}=\mathrm{ii}$
Hence only ' $A$ ' is correct.
