Answer 2

A hormone that controls closure of stomata response to water stress is Abscisic acid.

Among these, abscisic acid (ABA), is the best-known stress hormone that closes the stomata, although other phytohormones, such as jasmonic acid, brassinosteroids, cytokinins, or ethylene are also involved in the stomatal response to stresses.

I hope you got the answer.
