Quizplus · Accepted Answer

The vitamin necessary for the synthesis of prothrombin is vitamin K, and we get most of it from the bacteria in our colon. Therefore, option D is the correct choice. Option A is incorrect because it suggests that vitamin K is obtained from the food we eat, which is not entirely true. While some foods such as green leafy vegetables contain vitamin K, most of it is synthesized by the bacteria in our colon. Option B is incorrect because it suggests that we obtain vitamin C from the liver, which is incorrect. Option C is also incorrect because it suggests that vitamin C is obtained from colon bacteria, whereas it is well known that vitamin C is obtained from fruits and vegetables.
