C: Hemophilia B is due to a deficiency or absence of factor IX, another clotting protein, resulting in similar symptoms as Hemophilia A.
D: Von Willebrand disease is caused by a deficiency or dysfunction of von Willebrand Factor, not an excess production.
Summary:
B: Von Willebrand disease is not caused by an excess production but by a deficiency or dysfunction of von Willebrand Factor.
E: Hemophilia A is not due to fibrinogen deficiency but factor VIII deficiency.
F, G: These options are not relevant to the differences in causes of hemophilia A, hemophilia B, and von Willebrand disease.
