Right Answer is: A

SOLUTION

Plants usually perform respiration during the night as they do not have sunlight for photosynthesis and thus they give out a lot of carbon dioxide. A person sleeping under a tree during the night, therefore, inhales more carbon dioxide which deprives his body of oxygen. This leads to less energy production in his body, thus making him feel lethargic after he wakes up in the morning.
