The correct statement is:
d. they are expressed in males and can be masked in females if the female's second x chromosome is normal.
X-linked recessive disorders generally manifest in males, who have only one X chromosome. In females, who have two X chromosomes, the presence of a normal allele on the second X can mask the effects of the mutated allele on the first X.
