Solution
The correct option is B Tryptophan
Tryptophan is a aromatic amino acid which acts as a precursor to the neurotransmitter. It helps in biosynthesis of proteins. It also helps in the synthesis of niacin and auxin. It is made up of α-amino group, an α-carboxylic acid group, and a side chain indole. It acts as a precursor of serotonin and IAA. It synthesizes serotonin by enzyme tryptophan hydroxylase and IAA by tryptophan.So, the correct answer is option A.
