Option B

Explanation:

A father genotype for male sexuality is X'Y

Since he possess an X - linked disorder, thus in case if it is crossed with a mother with XX genotype

Thus, X'Y * XX

X'X, X'X, XY, XY

Thus, it is clear that a male child will carry Y chromosomes from his father and X chromosome from her mother. Thus, in order to have X-linked disorder, the male child must receive an affected X allele from his mother.

Hence, the probability of son inheriting an X-linked disorder from his father would be zero.
