Which of the following disorders is a deficiency of factor VIII?
Correct answer
A
Rationale
Hemophilia A is caused by a deficiency of factor VIII, leading to problems with blood clotting. Hemophilia B is caused by a deficiency of factor IX, not factor VIII. Christmas disease is another name for Hemophilia B, which is caused by a deficiency of factor IX. Sickle cell disease is a genetic disorder affecting hemoglobin, not a clotting factor deficiency.
