Answer

Brief Explanations:

In X - linked recessive inheritance, daughters inherit one X - chromosome from each parent and sons inherit their X - chromosome from their mother. The father's genotype is unknown, but the daughters have one affected allele ($X^a$) and one normal allele ($X^A$), and the son is normal ($X^A$). The mother must have at least one $X^a$ allele to pass it to the daughters and can have either a normal or a mutant allele on her other X - chromosome.

Answer:

C. $X^AX^a$
