Which of the following is a water soluble vitamin?

Vitamin C is classified as a water-soluble vitamin, which means it dissolves in water and is readily absorbed into the bloodstream. It plays several crucial roles in the body, including acting as a powerful antioxidant, aiding in collagen synthesis, and supporting the immune system. Since it is water-soluble, any excess amounts of vitamin C that the body does not need are excreted in urine, which differentiates it from fat-soluble vitamins.

In contrast, vitamins A, D, and E are all fat-soluble vitamins. They require the presence of dietary fat for proper absorption and storage in the body. They tend to accumulate in the body and can lead to toxicity if consumed in excessive amounts, which is not a concern with water-soluble vitamins like vitamin C. This distinction is important in nutrition and understanding how different vitamins function and are utilized by the body.
