QUESTION
Bleeding diathesis occurs due to deficiency of?
OPTIONS
(A) Vitamin K
(B) Vitamin E
(C) Vitamin C
(D) Vitamin D
ANSWER
(A) Vitamin K
EXPLANATION
Vitamin K is essential for hepatic synthesis of several clotting factors, including factors II, VII, IX, and X; deficiency therefore causes impaired coagulation and a bleeding diathesis. Vitamins E, C, and D have important biological functions but are not the principal vitamin responsible for synthesis of these vitamin K-dependent clotting factors. Thus, option A is correct.
