In brief: Clotting factor.

Hemophilia a results from a deficiency in clotting factor viii.
In contrast, hemophilia b (also called christmas disease) is caused by a deficiency in clotting factor ix. Hemophilia a is more common than hemophilia b, and people with hemophilia a are more likely to suffer from severe disease. It would be impossible to distinguish the two on clinical presentation alone.

In brief: Hemophilia

is a family of clotting disorders which result in decreased ability to clot the blood.
The difference between Hemophilia A and B is which of the clotting factors the patient is missing. Hemophilia A patients are missing Factor VIII. Hemophilia B patients are missing Factor IX. Hope this helps!
