Which one of the following acids is a derivative of carotenoids?
A
Abscisic acid
B
Indole butyric acid
C
Indole-3-acetic acid
D
Gibberellic acid
Detailed Solution
Plant growth regulators belong to different chemical groups.
Abscisic acid (ABA) is a derivative of carotenoids.
Indole-3-acetic acid and indole butyric acid are indole compounds (auxins).
Gibberellic acid ($GA_3$) is a terpene; kinetin is an adenine derivative and ethylene is a gas.
Hence the carotenoid derivative is abscisic acid.
