Fat-soluble vitamins are those that are soluble in fats and oils and can be stored in the body's fatty tissues and liver. They play crucial roles in various bodily functions and can be absorbed more efficiently when consumed with dietary fat. The vitamins that are classified as fat-soluble include A, D, E, and K. Vitamin A is essential for vision and immune function, vitamin D is important for bone health and calcium absorption, vitamin E acts as an antioxidant and protects cell membranes, and vitamin K is necessary for blood clotting and bone metabolism. These vitamins differ from water-soluble vitamins, which are generally not stored in the body and need to be consumed more regularly. The correct answer reflects this classification of vitamins, confirming their categorization as fat-soluble.
