A Correct answer
Explanation

Vitamin K is essential for the synthesis of clotting factors in the liver, particularly factors II, VII, IX, and X, which are required for proper blood coagulation. A deficiency of vitamin K leads to impaired blood clotting, resulting in excessive bleeding and poor wound healing. This is distinct from scurvy (vitamin C deficiency) and pernicious anemia (vitamin B12 deficiency).
