Q. Water stress causes the stomata to …A… hence reducing the …B… availability. Here A and B refer to
A) A-open; B-$H_{2}O$
B) A-close; B-$H_{2}O$
C) A-close; B-${CO}_{2}$
D) A-open; B-${CO}_{2}$
Explanation
A-Close, B-$CO_{2}$. Water stress causes the stomata to close hence, reducing the $CO_{2}$ availability
