Answer:

Option (C).

Explanation:

Sex linked disorder may be defined as the disorders that are caused by the mutation or defects in the sex chromosome. Two main types of sex linked disorder are sex linked recessive and sex linked dominant.

Hemophilia is caused due to the defect in the clotting factor. This is a sex linked recessive disorder that are transferred from female to their sons. The hemophilic father has only one X chromosome and they will transfer this affected X chromosome to their daughters and none of their sons. Since, sons receive Y chromosome from their father.

Thus, the correct answer is option (C).
