Correct option (a) Excessive transpiration
Explanation :
Osmotic pressure in the leaf cells is positive during excessive transpiration. Transprration is a physical and physiological process in which aerial parts of a living plant remove water in the form of vapours.
As the water is lost from the leaf surface by transpiration, osmotic pressure of the leaf calls increases.
