Which fat soluble vitamin helps in synthesis of prothrombin?

• A. Vitamin K
• B. Vitamin A
• C. Vitamin B
• D. Vitamin C

Answer 1

The correct option is A Vitamin K

Vitamin B and vitamin C are both water soluble. Vitamin A and K are fat soluble. Vitamin A has no role in the synthesis of prothrombin. Vitamin K plays a key role in helping the blood clot, preventing excessive bleeding. Vitamin K activates prothrombin to help in clotting.
