Which statement about vitamin K is true?

  1. It is a fat-soluble vitamin

  2. It is involved in carbohydrate metabolism

  3. It is stored in the muscle tissues

  4. It promotes vitamin C absorption

The correct answer is: It is a fat-soluble vitamin

The correct statement about vitamin K is that it is a fat-soluble vitamin. Fat-soluble vitamins, including vitamins A, D, E, and K, are absorbed along with dietary fats and stored in the body's fatty tissues and liver. This solubility affects how these vitamins are absorbed and metabolized in the body. In contrast, the involvement of vitamin K in carbohydrate metabolism or storage in muscle tissues is not accurate. Vitamin K's primary role is related to blood clotting and bone health, rather than carbohydrate metabolism. Additionally, it does not promote vitamin C absorption; these vitamins have distinct functions and mechanisms in the body.
