Which vitamins are classified as fat-soluble vitamins?

  1. Vitamins B, C, D, and E

  2. Vitamins A, D, E, and K

  3. Vitamins A, B, C, and K

  4. Vitamins D, E, F, and G

The correct answer is: Vitamins A, D, E, and K

Fat-soluble vitamins are those that are soluble in fats and oils and are typically stored in the body's fatty tissues and liver. The vitamins classified as fat-soluble include Vitamins A, D, E, and K. Vitamin A plays a crucial role in vision, immune system function, and skin health. Vitamin D is essential for calcium absorption and bone health, as well as immune function. Vitamin E acts as a powerful antioxidant, helping to protect cells from damage, and Vitamin K is vital for blood clotting and bone health. The other options include water-soluble vitamins, such as the B vitamins and Vitamin C, which do not fall into the category of fat-soluble vitamins. Hence, the correct response identifies the accurate group of fat-soluble vitamins.
