The correct option is C Tropical rainforests
The tropical rainforests are confined to areas of heavy rainfall. Areas which receive more than 200 cm of rainfall and have a short dry season are the best area for tropical rainforest. Almost all kinds of vegetation, like trees, shrubs and creepers, are found in such a forest. Ebony, mahogany, rosewood, rubber, and cinchona are some of the commercially important trees of tropical rainforests.
