The correct answer is (a) Vitamin-K.
Vitamin K is a group of fat-soluble vitamins that are essential for blood clotting. It is also involved in bone metabolism and wound healing. Vitamin K is found in green leafy vegetables, broccoli, Brussels sprouts, cabbage, and liver. It is also available as a supplement.
Vitamin A is essential for vision, growth, and development. It is found in animal products such as liver, eggs, and dairy products, as well as in plant-based foods such as carrots, sweet potatoes, and dark leafy greens.
Vitamin D is essential for bone health and immune function. It is found in fatty fish, eggs, and dairy products, as well as in sunlight.
Vitamin C is essential for the immune system and for the production of collagen, a protein that is found in skin, bones, and connective tissue. It is found in citrus fruits, tomatoes, and broccoli.
Vitamin K is the only vitamin that is essential for blood clotting. It does this by helping the body produce proteins that are involved in the clotting process. Vitamin K deficiency can lead to bleeding problems.
