Easy way to remember: Fat-soluble vitamins = A, D, E, K (think "ADEK"). All B-complex vitamins and Vitamin C are water-soluble and need daily replenishment.
To determine which vitamin is water-soluble, it's important to understand the division of vitamins based on their solubility. Vitamins can be classified into two categories: fat-soluble and water-soluble.
Fat-soluble vitamins include vitamins A, D, E, and K. These vitamins dissolve in fat and are stored in the body's fatty tissue.
Water-soluble vitamins include the B-complex group and vitamin C. These vitamins dissolve in water and are not stored in the body; hence, they need to be consumed regularly.
Let's analyze each option:
Vitamin A: This is a fat-soluble vitamin.
Vitamin C: This is a water-soluble vitamin. It must be replenished regularly because it is not stored in the body.
Vitamin D: This is a fat-soluble vitamin.
Vitamin K: This is also a fat-soluble vitamin.
Therefore, the correct answer is Vitamin C, as it is the only water-soluble vitamin among the options provided.
