Question
Which of the following vitamin helps during blood
clotting?Solution
Vitamin K is used by the body to help blood clot. Blood clotting, or coagulation, is an important process that prevents excessive bleeding when a blood vessel is injured. Platelets (a type of blood cell) and proteins in your plasma (the liquid part of blood) work together to stop the bleeding by forming a clot over the injury. Hence, option C is correct.
