Vitamins that dissolve in water and are excreted in urine when consumed in excess are called?

• A. Fat soluble
• B. Insoluble
• C. Vitamin
• D. Water soluble

Answer: (D)

Vitamins are grouped by how they dissolve and are stored in the body. Those that dissolve in water are not stored in large amounts; any excess tends to be eliminated through the urine. Because they’re not kept long-term in the body's tissues, you need to regularly obtain them from your diet.

In contrast, fat-soluble vitamins dissolve in fat and are stored in the liver and body fat. If you take too much, they can accumulate and potentially cause toxicity.

So, vitamins that dissolve in water and are excreted in urine when consumed in excess are the water-soluble ones. The other options don’t fit because fat-soluble refers to a different storage pattern, insoluble isn’t a standard vitamin category, and vitamin alone doesn’t specify solubility.
