Question

Which one is correctly matched?

• A. Vitamin A - Thiamine
• B. Vitamin D - Riboflavin
• C. Vitamin B${}_{12}$ - Cyanocobalamin
• D. Vitamin D - Tocopherol

Answer 1

The correct option is C Vitamin B${}_{12}$ - Cyanocobalamin

Thiamine, vitamin B${}_1$, is a sulphur containing thio vitamin. The chemical name of vitamin A is retinol or retinal which makes option A mismatch.

Vitamin B${}_{21}$ is chemically known as riboflavin while the chemical name for vitamin D is cholecalciferol which makes options B and D mismatch. Vitamin B${}_{12}$ is derivative of cyanocobalamin which makes option C correct match.

Thus, the correct match is option C.
