Solution

The correct option is A ABA deficiency
Abscisic acid (ABA) promotes closing of stomata under the condition of water stress (wilting). ABA play a significant inhibitory role, notably during physiological stress, e.g., drought, water logging etc. Deficiency of ABA in plant cells causes wilting.
