Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Because mesophytes face moderate conditions, they have:
A
A cuticle on the upper surface of the leaf only
B
Stomata that are open during the day
C
Low surface area to volume ratio
D
Vacuoles that store salt
Explanation: 

Detailed explanation-1: -Mesophytes generally require a more or less continuous water supply. They usually have larger, thinner leaves compared to xerophytes, sometimes with a greater number of stomata on the undersides of leaves.

Detailed explanation-2: -Mesophytes require abundant available soil water and a relatively humid atmosphere.

Detailed explanation-3: -The leaves of these plants have raised stomata that are above the epidermis. In addition, stomata are found on both sides of the leaves. This allows gaseous exchange and water loss (transpiration) to take place efficiently.

Detailed explanation-4: -Mesophytic plants have rigid, sturdy, freely branched stems and fibrous, well-developed root systems– either fibrous roots or long taproots. The leaves of mesophytic plants have a variety of leaf shapes, but they are generally flat, thin, relatively large, and green in color.
