Solution
The correct option is D Both Assertion and Reason are incorrect
The intercellular spaces of the transpiring organs is almost saturated
with water vapours. When the stomata are open the water vapours are
drawn from the substomatal cavities to the outside air due to high DPD
of the latter. This increase the DPD of the substomatal air which draws
more water vapours from the intercellular spaces. The latter in turn get
water vapours from the wet walls of mesophyll cell.
So, the correct answer is 'Both Assertion and Reason are incorrect'.
