Options

AIndole compound
BAdenine derivative
CCarotenoid derivative
DTerpene

Correct answer

D. Terpene

Step-by-step solution

The plant growth regulators (PGRs) are small, simple molecules of diversechemical composition . They could be indole compounds (indole-3-acetic acid, IAA); adenine derivatives (N6 -furfurylamino purine, kinetin), derivatives of carotenoids (abscisic acid, ABA); terpenes (gibberellic acid, GA3) or gases (ethylene, C2H4)
