They are found in the hot wet forests of Assam, Karnataka and Kerala. These areas have huge forest, which are very suitable for elephants.

Elephants are found in the hot-wet forests of Assam and Karnataka.

Assam:
- Assam is located in the northeastern part of India and is known for its lush green forests and diverse wildlife.
- The state is home to several national parks and wildlife sanctuaries, including Kaziranga National Park, Manas National Park, and Nameri National Park.
- These protected areas provide a suitable habitat for elephants, as they offer a combination of dense forests, grasslands, and water bodies.
- The hot-wet climate of Assam, with its high rainfall and humidity, creates an ideal environment for the growth of vegetation that elephants depend on for food and water.

Karnataka:
- Karnataka is a state in the southern part of India, characterized by a diverse landscape ranging from coastal areas to the Western Ghats.
- The state is known for its rich biodiversity and is home to several national parks and wildlife sanctuaries, including Bandipur National Park, Nagarhole National Park, and Bannerghatta National Park.
- These protected areas, along with the adjoining forests, provide a suitable habitat for elephants.
- Karnataka's hot-wet forests receive significant rainfall, which supports the growth of a variety of plants that elephants feed on.

Why not the other options?

Punjab and Haryana:
- Punjab and Haryana are primarily agricultural states located in the northern part of India.
- These regions are characterized by a semi-arid climate, with relatively low rainfall and high temperatures.
- The hot and dry conditions in these states are not favorable for the survival of elephants, as they require a habitat with abundant water sources and vegetation.

Rajasthan and Gujarat:
- Rajasthan and Gujarat are arid states located in western India.
- The Thar Desert spans across these regions, making them unsuitable for elephants.
- The extreme heat and scarcity of water in these areas make it difficult for elephants to thrive.

West Bengal and Jharkhand:
- West Bengal and Jharkhand are states in eastern India, but they do not have hot-wet forests suitable for elephants.
- West Bengal has a diverse range of ecosystems, including the Sundarbans mangrove forests and the foothills of the Himalayas, but these areas are not known for supporting a significant elephant population.
- Jharkhand, on the other hand, is known for its mineral-rich landscapes and forests, but it does not have the hot-wet climate that elephants prefer.

In conclusion, elephants are found in the hot-wet forests of Assam and Karnataka, as these regions provide the ideal habitat with abundant water sources and vegetation for their survival.
