Question

The water soluble vitamin which is not excreted through urine easily is

• A. Vitamin B$_{12}$
• B. Vitamin C
• C. Vitamin B$_1$
• D. Vitamin B$_6$

Hint:

Remember that Vitamin B$_{12}$ is an exception among water-soluble vitamins due to its storage and slow excretion.

Answer 1

The Correct Option is A

Among the water-soluble vitamins, Vitamin B$_{12}$ (cobalamin) is unique because it is stored in significant amounts in the liver and not easily excreted through urine. Other water-soluble vitamins are typically excreted quickly when in excess.
