Which of the following nutrients is categorized as a B vitamin?

1. Ascorbic acid

2. Riboflavin

3. Folic acid

4. Vitamin E

The correct answer is: Riboflavin

Riboflavin is categorized as a B vitamin, specifically known as vitamin B2. It plays a crucial role in energy production and the metabolism of fats, drugs, and steroids, as well as in the maintenance of healthy skin and eyes. Present in various food sources such as eggs, green leafy vegetables, and dairy products, riboflavin is essential for producing red blood cells and enhancing overall cellular function. Ascorbic acid, also known as vitamin C, is not a B vitamin but rather an antioxidant that plays vital roles in immune function and collagen synthesis. Folic acid, while also important, is categorized as vitamin B9, which means it is a B vitamin but isn’t the answer to this specific question. Vitamin E is a fat-soluble vitamin known for its antioxidant properties, but it is not classified under the B vitamins. Therefore, riboflavin is the correct focus as it directly aligns with the classification of B vitamins.
