Answer

The correct answer would be B) 50 %.

In humans, the blood group is determined by three alleles $I^{A},I^{B},$ and $i$ .

$I^{A} and I^{B}$ are co-dominant whereas $i$ is recessive to other two.

Thus, the genotype of a person with blood group O would be $ii$ .

The genotype of a person with blood group B would be either $I^{B}I^{B}$ (homozygous condition) or $I^{B}i$ (heterozygous condition).

The crosses are shown in the image below.

There is only one condition in which the person can have offspring with blood group O that is, when the other parent is $I^{B}i$ .

In this condition, the probability of an offspring to have blood group O is 50%.

In other condition, the probability of an offspring to have blood O is 0%.
