Solution

The correct option is D Closes
Guard cells get swollen up or turgid due to absorption of water so the stomatal pore is opened up.
When the turgidity is lost they lose their shape and cause the closing of the stomatal pore.
Plasmolysis occurs when cells are placed in hypertonic solutions.
So the correct answer is 'Closes'.
