Solution

The correct option is B Tryptophan
Nicotinamide is a vitamin. It is also called Vitamin B3. It plays a vital role in the synthesis of components necessary for the production of ATP. It acts as an electron carrier and it helps in the interconversion of energy between nutrients and the ATP. It is a non-essential vitamin as humans can synthesize it in the body. It can be synthesized in our body from tryptophan amino acid in the liver. 60 mg of tryptophan is required to take 1 mg of the vitamin.
Thus, the correct answer is 'Tryptophan.'
