The opening and closing of stomata is dependent on the turgidity of the guard cells. Active excretion of hydrogen ions from the guard cells facilitates the movement of K+ into the guard cells . This allows uptake of water by osmosis thus making guard cells turgid and the stoma opens.
Increased turgidity is responsible for opening of stomata. Hence, option (d) is correct.
