Question

Which of the following disorders results from a deficiency of factor VIII?

a. Sickle cell disease
b. Christmas disease
c. Hemophilia A
d. Hemophilia B

Answer 1

(c). Hemophilia A

Step-by-step explanation:

Hemophilia A can be defined as a genetic disorder, characterized by severe external or internal bleeding. Hemophilia A is caused by defective or missing factor VIII, due to mutation in gene for factor VIII that leads to formation of a non-function or truncated clotting protein.

Factor VIII is a blood clotting protein, which prevents excessive blood loss during injury. Hence, deficiency of factor VIII can leads to development of hemophilia A.

Thus, the correct answer is option (c).
