Verified step by step guidance

1. Understand that fat-soluble vitamins are vitamins that dissolve in fats and oils and are stored in the body's fatty tissue and liver. The main fat-soluble vitamins are Vitamins A, D, E, and K.
2. Recognize that Vitamin A, Vitamin D, and Vitamin E are all fat-soluble vitamins, meaning they require dietary fat for absorption and can be stored in the body for longer periods.
3. Identify that Vitamin C is a water-soluble vitamin, which means it dissolves in water, is not stored in large amounts in the body, and excess amounts are usually excreted in urine.
4. Recall that water-soluble vitamins include Vitamin C and the B-complex vitamins, which need to be consumed more regularly because they are not stored extensively.
5. Conclude that since Vitamin C is water-soluble and not fat-soluble, it is the correct answer to the question asking which vitamin is NOT fat-soluble.
