The correct answer is: a) High rainfall.
Tropical evergreen forests are found in areas of Tamil Nadu receiving high rainfall. These forests are characterized by a dense canopy of trees that are evergreen, meaning they keep their leaves all year round. The trees in these forests are adapted to the high rainfall by having deep roots that can reach water deep underground. They also have thick, waxy leaves that help to prevent water loss.
The high rainfall in these forests provides the water that the trees need to survive. The trees also provide a home for a variety of animals, including birds, insects, and mammals. These forests are an important part of the environment and play a role in regulating the climate.
The other options are incorrect because they do not provide the necessary conditions for tropical evergreen forests to grow. Moderate rainfall is not enough to support these forests, and low rainfall would not provide enough water for the trees to survive. Seasonal rainfall would also not be enough, as the trees need a constant supply of water to survive.
In conclusion, the correct answer to the question “Tropical evergreen forests are found in areas of Tamil Nadu receiving:” is a) High rainfall.
