Verified step by step guidance

1. Step 1: Understand the classification of vitamins into fat-soluble and water-soluble categories. Fat-soluble vitamins dissolve in fats and oils and are stored in the body's fatty tissues, while water-soluble vitamins dissolve in water and are not stored extensively in the body.
2. Step 2: Recall the list of fat-soluble vitamins, which include Vitamins A, D, E, and K. These vitamins require dietary fats for proper absorption and can be stored in the liver and adipose tissue.
3. Step 3: Identify Vitamin C as a water-soluble vitamin, meaning it dissolves in water, is not stored in large amounts in the body, and must be consumed regularly through the diet.
4. Step 4: Compare the options given: Vitamin A, Vitamin D, and Vitamin E are all fat-soluble, whereas Vitamin C is not.
5. Step 5: Conclude that Vitamin C is the vitamin that is NOT fat-soluble, distinguishing it from the other options.
