Question

Which of the following vitamins is water-soluble?

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

Hint:

Remember the solubility properties of vitamins: water-soluble vitamins (like B-complex and C) need to be consumed regularly as they are not stored in significant amounts by the body, while fat-soluble vitamins (like A, D, E, K) can be stored and may accumulate to toxic levels if overconsumed.

Answer 1

The Correct Option is A

Step 1: Two kinds of vitamins.
Vitamins split into two groups. Water soluble vitamins dissolve in water, and fat soluble vitamins dissolve in fat.
Step 2: Which dissolve in water.
The water soluble vitamins are the B group and vitamin C. These are not stored much and extra amounts leave in urine.
Step 3: Which dissolve in fat.
The fat soluble vitamins are A, D, E and K. These can be stored in the body fat and the liver.
Step 4: Check vitamin C.
Vitamin C is ascorbic acid. It is one of the water soluble vitamins, so it dissolves in water.
Step 5: Check the others.
Vitamin A, vitamin D and vitamin K all belong to the fat soluble group. So they do not dissolve in water.
Step 6: Final choice.
Among these, only vitamin C is water soluble.\[ \boxed{\text{Vitamin C}} \]
