C Correct answer
Explanation

Vitamin K is essential for producing clotting factors (prothrombin and factors II, VII, IX, X) in the liver - without it, blood cannot properly clot. The 'K' comes from 'koagulation' (German for clotting). Vitamin D regulates calcium, Vitamin E is an antioxidant, and B12 supports nerve function.
