Which one of the following pairs is not correctly matched:
- Vitamin C–Scurvy
Vitamin B2–Pellagra
Vitamin B12–Pernicious anaemia
Vitamin B6–Beri-beri
The Correct Option is D
Solution and Explanation
Beri-Beri is caused by a deficiency of vitamin B1 (thiamine), not vitamin B6 (pyridoxine).
So, the correct option is (D): Vitamin B6–Beri-beri

Concepts Used:
Vitamins
Vitamins are natural and essential nutrients. In the growth and development of the human body it plays an important role. For proper growth, strong bones and good development needs the right quantity of vitamins in our body. These vitamins are organic substances that work in groups for the normal and smooth functioning of our body cells.
Types of Vitamins:
There are two main types of vitamins.
Fat-Soluble Vitamins-
Fat-soluble vitamins are stored in the fat cells. These vitamins require fat in order to be absorbed. Vitamin A, D, E and K are fat-soluble vitamins.
Water-Soluble Vitamins-
Water-soluble vitamins are not stored in our body because its excess gets excrete through the urine. Therefore, these vitamins need to be replenished constantly. Vitamin B and C are water-soluble vitamins.
