Solution

The correct option is B A-3, B-1, C-5, D-4, E-2
Plant hormones can be of 5 types.
Indole Compounds - $I A A$
Adenine derivatives - Kinetin
Derivatives of carotenoids - $A B A$
Terpenes - $G A_{3}$
Gases - $C_{2} H_{4}$

Kinetin is a type of cytokinin, a plant hormone. Cytokinin is an adenine derivative. Gibberellic acid is a terpene chemically. Abscisic acid is a plant hormone which is carotenoid derivative. IAA (indoleacetic acid) is an indole compound. It is a plant hormone which acts as a growth promoter. $C_{2} H_{4}$ is ethylene gas which acts as a plant hormone.
