Solution

The correct option is B Vitamin K
Vitamin K refers to a group of structurally similar, fat-soluble vitamins the human body needs for complete synthesis of certain proteins that are required for blood coagulation and also certain proteins that the body uses to control binding of calcium in bone and other tissues. Without vitamin K, blood coagulation is seriously impaired and uncontrolled bleeding occurs.
