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
