B Correct answer
Explanation

Vitamin K is essential for the synthesis of clotting factors in the liver, including prothrombin and factors II, VII, IX and X. Without adequate vitamin K, blood cannot clot properly, leading to excessive bleeding. Reproduction is controlled by hormones, while carbohydrate and amino acid metabolism involve different vitamin complexes.
