How can the opposite effects of gibberellin and abscisic acid be understood?
Answer and explanation
Correct answer: Gibberellin may promote growth and abscisic acid may inhibit growth
The governing concept is the action of plant hormones. Gibberellin generally promotes stem elongation, seed germination, and other growth-related processes, whereas abscisic acid commonly inhibits growth and supports dormancy or stress responses. Therefore, option A correctly describes their contrasting effects. The other choices refer to animal physiology and do not describe plant hormones.
