Answer 1

Answer: (A)

Auxin is chemically known as indole 3 acetic acid (IAA) is an indole compound that is formed from an amino acid, tryptophan. Kinetin is a modified form of adenine, a purine, isolated by autoclaving herring fish sperm DNA. Abscisic acid is derived from carotenoids. Gibberellic acids are terpenes that occur in different forms.
