C Correct answer
Explanation

Vitamin K is essential for the synthesis of clotting factors in the liver, specifically factors II (prothrombin), VII, IX, and X. Without adequate vitamin K, blood cannot clot properly, leading to excessive bleeding. Vitamins A, B, and D have important functions but are not involved in the coagulation cascade.
