Which of the following are the four fat-soluble vitamins?

The four fat-soluble vitamins are A, D, E, and K. These vitamins are absorbed along with dietary fat and are stored in the body's fatty tissue and liver, contributing to their stability and retention in the body compared to water-soluble vitamins.

Vitamin A is important for vision, immune function, and skin health. Vitamin D plays a crucial role in calcium absorption and bone health. Vitamin E acts as an antioxidant, protecting cells from damage, while vitamin K is essential for blood clotting and bone metabolism.

In contrast, water-soluble vitamins, such as those in the choices that include C and the B vitamins, do not get stored in the body in significant amounts and are excreted in urine, which is why they need to be consumed more regularly. This distinction highlights the unique properties and functions of fat-soluble vitamins in nutrition and health.
