Vedclass · Answer

(B) Abscisic acid $(ABA)$ is a natural growth inhibitor. It promotes stomatal closure,acting as a stress hormone that helps the plant cope with adverse environmental conditions,especially drought. It also induces dormancy in seeds and buds,ensuring they remain inactive until favorable conditions return. These seeds sprout only when the inhibitory effect of $ABA$ is overcome by $GA$ (Gibberellic Acid).
