Answer 1

The correct choice is (c) Because of trees overlap with each other

The explanation is: Evergreen forests look green throughout the year due to high rainfall. The trees overlap with each other to form a continuous canopy. Thus, little light penetrates down to the forest floor. The forest is rich in orchids and ferns.
