Solution
The correct option is C Abscisic Acid
Abscisic acid is a naturally occurring plant hormone. It stimulates the closure of stomata in the epidermis during water stress conditions. So, water loss through the stomata by transpiration is reduced and it is therefore known as antitranspirant hormone. This hormone increases the tolerance of plants to various kind of stresses in the environment. Hence it is also called stress hormone. Thus the correct answer is option C.
