Hint: The tropical evergreen forests are also called tropical rainforests. These thick forests occur in the regions close to the tropics and near the equator. These regions receive heavy rainfall throughout the year and are hot; this is the reason why these forests have luxuriant vegetation of all kinds- trees, shrubs, and creepers.
Complete step-by-step solution:
There are three broad categories of natural vegetation. These are Forests, Grasslands, and Shrubs. The changes in the type of natural vegetation occur mainly because of the changes in climatic conditions. Among these, forests can grow where rainfall and temperature are plentiful to support a tree cover. Depending upon these factors, open and dense forests are grown. Further, there are many types of forests which are Tropical Evergreen Forests, Tropical Deciduous Forests, Temperate Evergreen Forests, Temperate Deciduous Forests, Mediterranean Forests, and lastly Coniferous Forests.
As there is no particular dry season, the trees in evergreen forests do not shed their leaves altogether. That is why they are called evergreen. In the daytime, even inside the forest, the thick canopies of the closely spaced trees do not allow the sunlight to penetrate. Hardwood trees like ebony, rosewood, mahogany, rubber, and Cinchona are common here. Deer, monkeys, elephants, and lemurs are the common animals in these forests. Not only that, plenty of sloths, birds, bats, snails, and scorpions.
The Evergreen forests of Karnataka can be found in parts of Chamarajnagar, Chikkamagaluru, Dakshina Kannada, Hassan, Kodagu, Shivamogga, and Uttara Kannada districts. Different types of tall trees like rosewood, mahogany, kino, teak, dhupa, and hebbalasu grow in these forests.
Thus, option (A) is correct.
Note: Dhupa trees grow mostly in the Western Ghats of India in moist evergreen forests. Dhupa trees have also been extensively planted as avenue trees in parts of Kerala and Karnataka states. From January to March is the flowering time of these trees and the fruits ripen from May to July
