Q. Which of the following is responsible for opening and closing of stomata?

Transport in Plants

Solution:

Opening and closing of stomata are controlled by all the factors mentioned in the options. Rise in pH of guard cells causes hydrolysis of starch and so stomata open, cytokinin and cyclic AMP are required for stomatal opening and abscisic acid stops the K+ ions exchange and pH is decreased finally leading to closure of stomata.
