The correct answer is (d), Vitamin K. Vitamin K is essential for the production of clotting factors, which are proteins that help blood to clot. When vitamin K is deficient, the body cannot produce enough clotting factors, which can lead to bleeding disorders.
Vitamin A is important for vision, skin, and immune function. Vitamin D is important for bone health. Vitamin E is an antioxidant that protects cells from damage.
Bleeding disorders can also be caused by other factors, such as liver disease, kidney disease, and certain medications. If you are experiencing any bleeding problems, it is important to see a doctor to determine the cause and get treatment.
