Which set of vitamins is classified as fat-soluble?

Fat-soluble vitamins are those that can dissolve in fats and oils, allowing them to be stored in the body's fatty tissues and liver. The vitamins classified as fat-soluble include A, D, E, and K. Each of these vitamins plays a unique role in bodily functions. For example, vitamin A is essential for vision and immune function, vitamin D is crucial for calcium absorption and bone health, vitamin E acts as an antioxidant, and vitamin K is important for blood clotting.

In contrast, the other choices include water-soluble vitamins, such as the B vitamins and vitamin C, which do not have the same storage ability in the body and need to be consumed more regularly. This significant storage difference helps to outline the role of fat-soluble vitamins in nutrition, supporting the selection of A, D, E, and K as the correct group.
