Solution

The correct option is A
Abscisic acid

Abscisic acid (ABA) induces dormancy in seeds. Gibberellic acid (GA) breaks up the stored food in the seed by stimulating the production of enzymes which facilitates seed germination. ABA induces senescence while GA delays senescence. So, ABA is antagonistic to GA in most situations.
