Hi friend !
The ans is :- option (3) Abscisic acid
Abscisic acid (ABA) is a plant hormone which functions mainly as a growth inhibitor.
Abscisic acid promotes the dormancy in seeds and buds [ this is the opposite of breaking the dormancy].
It also promotes closing of stomata.
Abscisic acid promotes falling and wilting of leaves
