Vedclass · Answer

(C) The correct answer is $C$. Water stress occurs when the plant lacks sufficient water. To prevent excessive water loss through transpiration,the guard cells lose turgidity,causing the stomata to close ($A$-close). Since the stomata are the primary sites for gas exchange,their closure prevents the entry of atmospheric carbon dioxide into the leaf. Therefore,this reduces the availability of $CO_{2}$ $(B-CO_{2})$ for the process of photosynthesis.

Water stress causes the stomata to $A$ hence reducing the $B$ availability. Here $A$ and $B$ refer to:
