Answer 1

Hint:
In the equatorial region throughout the year, the temperature is high. The annual average temperature is about $27^\circ {\text{C}}$. Rainfall is distributed and heavy throughout the year. This region receives about 250cm annual average rainfall.

Complete Answer:
Evergreen forests are found in the Himalayas, Andaman and Nicobar Islands, the western slope of the Western Ghats, and hills of the north-eastern region. They are found in areas with annual precipitation of over 200 cm and in humid and warm areas. The mean annual temperature required for these forests is above $22^\circ {\text{C}}$. Tropical evergreen forests are well stratified, with short structured trees followed by a tall variety of trees, with layers closer to the ground and are covered with shrubs and creepers. Trees reach great heights up to 60 m or above in these forests. Here, there is no definite time for trees to shed their leaves, flowering, and fruition. All the year-round, as such these forests appear green.
Some of the commercially important trees of this forest are cinchona, mahogany, rosewood, aini, ebony, rubber, etc. The fauna found in these forests include deer, elephants, lemur, monkey, etc. In the jungles of West Bengal and Assam, the one-horned rhinoceros are found. In these jungles besides these animals, plenty of snails, bats, birds, sloths, and scorpions are also found.

Thus, option (D) is correct.

Note:
These evergreen forests occur in China, south-eastern Brazil, and parts of south-eastern North America. They are also found in temperate mid-latitudes of North America, Orinoco basins of South America, Scandinavia, Siberia, Australia, Canada, Africa, Indonesia, Malaysia, and Amazon basins.
