Fat Soluble and Water Soluble

• A. Two types of Vitamins
• B. One Type of Vitamin
• C. Three Types of Vitamins
• D. Four Types of Vitamins

Answer: (A)

Vitamins are classified by how they dissolve and are stored in the body. There are two main categories: fat-soluble vitamins, which dissolve in fat and are stored in the liver and fatty tissues, and water-soluble vitamins, which dissolve in water and are not stored in large amounts, so they need regular intake and any excess is excreted in urine. Examples of fat-soluble vitamins include A, D, E, and K; examples of water-soluble vitamins include vitamin C and the B vitamins. Because of this two-category split, the correct answer reflects two types of vitamins. The other options misstate the number of classifications, either suggesting only one or more than two, which doesn’t align with how vitamins are grouped by solubility.
