Hi!
The stomata plant's primary function is to regulate moisture loss from the plant. The upper portion of this leaf is more exposed to the air and sunshine since making water more susceptible to evaporation. On the other hand, the stomata is abundant on the lower surface, so the location of it will assist these plants with conserving more water.
Based off of this information, your correct answer choice would be "(B) the number of stomata is greater on the lower surface of the leaf."
Hope I could help!
