Solution

The correct option is A True
Transpiration:
It is the process of water loss in the form of water vapor from the aerial parts of the plants, such as leaves.
In the dorsiventral leaf of a dicot plant with an upper and a lower surface, the rate of transpiration is different on both surfaces.
The upper surface has fewer stomata as compared to a lower surface of a leaf.
Therefore, transpiration is greater at the lower surface of the leaf.
Final answer: The given statement is true.
