The correct answer is A) Western Ghats region.
The Western Ghats are a mountain range that runs along the western coast of India. They are a biodiversity hotspot and home to a wide variety of plant and animal life. The Western Ghats are also home to a number of tribal communities, who have lived in the region for centuries. These communities have a unique culture and way of life, which is closely tied to the environment.
The Western Ghats are a UNESCO World Heritage Site and are protected by law. However, they are under threat from a number of factors, including deforestation, mining, and development. It is important to protect the Western Ghats and the tribal communities that live there.
The other options are incorrect because:
- B) Coastal plains are not home to a large number of tribal communities.
- C) Deccan Plateau is home to a number of tribal communities, but not as many as the Western Ghats.
- D) Northern districts are not home to a large number of tribal communities.
