Which of the following is a water-soluble vitamin?

Rationale

Vitamin C is a water-soluble vitamin.

Vitamin C, also known as ascorbic acid, is a vital nutrient that dissolves in water, making it easily absorbed by the body and essential for various biological functions, including collagen synthesis and immune support.

A (A) YOUR ANSWER

Vitamin A is a fat-soluble vitamin, meaning it requires dietary fats for absorption and is stored in the body's fatty tissues and liver. It plays a crucial role in vision, immune function, and skin health, but it is not soluble in water.

B (C) CORRECT

Vitamin C is the only vitamin among the choices that is water-soluble. Its solubility allows it to be readily transported in the bloodstream and utilized by the body, making it essential for maintaining overall health and supporting various metabolic processes.

C (D) YOUR ANSWER

Vitamin D is another fat-soluble vitamin. It is primarily obtained from sunlight exposure and certain foods, and it plays a significant role in calcium absorption and bone health. However, it does not dissolve in water, distinguishing it from water-soluble vitamins.

D (E) YOUR ANSWER

Vitamin E is also a fat-soluble vitamin that functions primarily as an antioxidant, protecting cells from oxidative damage. Like vitamins A and D, it is stored in fat tissues and is not water-soluble.

E (K) YOUR ANSWER

Vitamin K is a fat-soluble vitamin crucial for blood clotting and bone metabolism. It is absorbed along with dietary fats and stored in the liver, making it fundamentally different from water-soluble vitamins.

Conclusion

Among the listed options, vitamin C stands out as the only water-soluble vitamin, which is crucial for various physiological functions. The other vitamins—A, D, E, and K—are all fat-soluble, highlighting the important distinction in how these nutrients are absorbed, stored, and utilized in the body. This knowledge is essential for understanding dietary needs and the role of vitamins in overall health.
