Which vitamin is an example of a water-soluble vitamin?

1. Vitamin D

2. Vitamin A

3. Vitamin B2

4. Vitamin E

The correct answer is: Vitamin B2

Vitamin B2, also known as riboflavin, is indeed an example of a water-soluble vitamin. Water-soluble vitamins are those that dissolve in water and are not stored in the body in significant amounts; they are excreted in urine. This means they need to be consumed regularly in the diet. Riboflavin plays a crucial role in various bodily functions, particularly in energy production and the metabolism of fats, drugs, and steroids. It also helps to maintain healthy skin, eyes, and nerve functions. In contrast, the other vitamins mentioned, such as Vitamin D, Vitamin A, and Vitamin E, are classified as fat-soluble vitamins. These vitamins require dietary fats for absorption and can be stored in the body’s fatty tissues and liver, which distinguishes them from the water-soluble vitamins.
