The term vitamin was coined from the word vital +amine since the earlier identified compounds had amino groups. Later work showed that most of them didn't contain amino groups, so the letter "e" was dropped and ther term vitamin is used these days.

Vitamins are classified into two groups depending upon their solubility in water or fat. Fat soluble vitamins are soluble in fat and oils but insoluble in water. They are stored in liver and adipose (fat storing) tissues.

Water-soluble vitamins are soluble in water. They must be supplied regularly in the diet as they are readily excreated in urine. 

Among the following, water-soluble vitamin is

Vitamin C

The correct answer is Option (3) → Vitamin C

Concept Used:

Water-soluble vitamins include Vitamin B-complex and Vitamin C.

Fat-soluble vitamins include Vitamins A, D, E, and K.

Explanation:

Option 1: Vitamin A

Vitamin A is a fat-soluble vitamin. It is stored in the liver and adipose tissues and does not dissolve in water. Therefore, it is not water-soluble.

Option 2: Vitamin D

Vitamin D is also fat-soluble. It dissolves in fats and oils and can be stored in the body for long periods. Hence, it is not water-soluble.

Option 3: Vitamin C

Vitamin C is a water-soluble vitamin. It dissolves in water and is not stored in the body in significant amounts. Excess is excreted through urine, which is a key characteristic of watersoluble vitamins.

Option 4: Vitamin K

Vitamin K is a fat-soluble vitamin. It is stored in body tissues and does not dissolve in water.
