Q. No.As per \(\mathrm{ABO}\) 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. \(\mathrm{I^{B}i / I^{A}i / ii}\)
B. \(\mathrm{I}^{\mathrm{B}} \mathrm{I}^{\mathrm{B}} / \mathrm{I}^{\mathrm{A}} \mathrm{I}^{\mathrm{A}} / \mathrm{ii}\)
C. \(\mathrm{I^AI^B/iI^A/I^Bi}\)
D. \(\mathrm{I^{A}i / I^{B}i / I^{A}i}\)
