Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
The second layer, the canopy, is formed by trees that grow between 60 and 150 feet tall (18-46 meters). The trees form a dense habitat that sustains most of the plant and animal life found in tropical rainforests. The canopy layer also serves as a sunshade for the rainforest below, absorbing a majority of the sunlight. Only about two to five percent of the sunlight penetrates the canopy and reaches the forest floor. Hence below the canopy layer, transpiration is not possible.
Therefore, the correct answer is option A.
