Question

_____ is a water soluble vitamin.

• A. Vitamin B
• B. Vitamin A
• C. Vitamin K
• D. Vitamin E

Hint:

Use the simple mnemonic "KADE" to remember all the fat-soluble vitamins (Vitamins K, A, D, and E). Any vitamin not in this group (such as B and C) is water-soluble.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Vitamins are essential organic micronutrients required by the human body in small quantities for various metabolic functions.
Based on their solubility characteristics, vitamins are broadly classified into two major groups:
1. Fat-Soluble Vitamins
2. Water-Soluble Vitamins
Detailed Explanation:
Water-soluble vitamins dissolve easily in water and are readily excreted from the body in urine.
Because they are not stored in significant amounts in bodily tissues, they require regular and continuous dietary replenishment.
The water-soluble group includes:
- Vitamin C (ascorbic acid)
- Vitamin B-complex group (including Thiamine, Riboflavin, Niacin, Pantothenic acid, Pyridoxine, Biotin, Folic acid, and Cobalamin).
In contrast, fat-soluble vitamins dissolve in organic solvents and fats.
They are absorbed along with dietary fats and stored in the liver and adipose tissues.
The fat-soluble vitamins are Vitamin A, Vitamin D, Vitamin E, and Vitamin K.
Comparing the options, Vitamin B is the only water-soluble vitamin listed.

Step 2: Final Answer:
Thus, Vitamin B is classified as a water-soluble vitamin.
