Solution
The correct option is D Cyanocobalamin
Vitamin B12 is also called cobalamin.
It is a water-soluble vitamin that is involved in the metabolism of every cell of the human body: it is a cofactor in DNA synthesis and in both fatty acid and amino acid metabolism.
Weakness and fatigue are common symptoms of vitamin B12 deficiency. These occur because your body doesn't have enough vitamin B12 to make red blood cells, which transport oxygen throughout your body.
Deficiency of vitamin b12 can lead to pernicious anaemia. Hence, Cyanocobalamin is vital for protein metabolism.
