Solution
The correct option is D A necessary evil
Transpiration is the loss of excess water in the form of water vapour through stomata, present on the aerial parts of the plants like leaves, stems, etc. Transpiration keeps the plants cool. Also, without transpiration, water and minerals will not rise from roots to aerial parts of plants and trees. At the same time, it is essentially a wasteful process for the plants. Most of the water absorbed by a plant goes waste into the atmosphere through transpiration. Thus, transpiration has been called a necessary evil for plants.
