Which category do vitamins A, D, E, and K belong to?

Explanation:
Fat-soluble vitamins are absorbed with fats and stored in the body. Vitamins A, D, E, and K fit this group because they dissolve in fat rather than water and require bile and dietary fat for proper absorption. They can be stored in the liver and adipose tissue, so daily intake isn’t essential, but consuming them in excess can lead to toxicity. This storage capability also means their status can be influenced by fat malabsorption or very low-fat diets. In contrast, water-soluble vitamins are not stored in large amounts and are typically excreted in urine, so they usually need more regular intake.
