Choice A rationale:

Hemophilia is a hereditary disorder caused by a deficiency of specific clotting factors, and it is indeed hereditary in nature. This statement is incorrect.

Choice B rationale:

Hemophilia is a bleeding disorder where the blood does not clot properly. Replacement therapy, which involves infusing clotting factor concentrates, is a standard treatment for hemophilia. This statement is correct.

Choice C rationale:

Hemophilia is an X-linked recessive genetic disorder, not dominant. Males are more commonly affected because they have only one X chromosome, and if it carries the defective gene, they will have hemophilia. Females have two X chromosomes, and if one X chromosome carries the defective gene, the other X chromosome can compensate, making them carriers but not typically affected.

Choice D rationale:

Hemophilia A is the most common form of hemophilia, not hemophilia B.
