Answer:

The correct answer is - C) B positive

Explanation:

In the given question is the man has B positive blood group with two offspring a girl with type O positive and a son who is type B negative. In ABO blood group A and B if present together they express in offspring if present together.

Here the difference in the Rh factor only as the blood group O has no antigen on its surface therefore the most possible phenotype for the father as he has son with B negative and a daughter with O positive.
