In sex-linked inheritance of a recessive gene, the gene is located on the X chromosome. Males have one X chromosome and one Y chromosome, while females have two X chromosomes. If a male receives the mutant X chromosome from his mother, he would show the trait, as he only has one X chromosome. Females, on the other hand, need to receive two copies of the mutant gene (one from each parent) to show the trait, so they are usually carriers. Therefore, choice C is the best answer as it correctly describes the inheritance pattern of a sex-linked recessive trait.
