Which list contains only fat-soluble vitamins?

• A. A, D, E, K
• B. B, C
• C. A, B, C, D
• D. C, D, E

Answer: (A)

Fat-soluble vitamins are A, D, E, and K. They are absorbed with dietary fats and stored in the liver and adipose tissue, so they can accumulate if consumed in excess and are not excreted as quickly. Water-soluble vitamins, like B-complex vitamins and vitamin C, are not stored to the same extent and are excreted in urine, requiring regular intake. The list that contains only fat-soluble vitamins is the one with A, D, E, and K, since the other options include B and/or C, which are water-soluble.
