Explanation: Kerala is a state located in the south-western part of India. It is one of the smallest states in India but is renowned for its natural beauty, cultural richness, and high standards of living. The state is bordered by the Arabian Sea to the west and the Western Ghats to the east, which contribute to its unique geography and climate.
The Western Ghats, a mountain range that runs parallel to the western coast of India, plays a significant role in the state's geography. These mountains not only provide a natural boundary but also influence the climate and biodiversity of the region. Kerala experiences a tropical climate with high humidity and receives heavy rainfall, especially during the monsoon season.
Kerala is known for its extensive network of backwaters, which are a series of interconnected canals, rivers, lakes, and lagoons. These backwaters are a major tourist attraction and are an integral part of the state's identity. The state is also famous for its beaches, which stretch along the Arabian Sea, and its lush green landscapes, which are a result of the abundant rainfall and fertile soil.
In contrast, Karnataka, located to the north-east of Kerala, is known for its diverse geography, including the Western Ghats and the Deccan Plateau. Karnataka is not in the south-western part of India, but rather in the southern-central region. It is known for its historical sites, such as Hampi and Mysuru, and its cultural diversity.
Maharashtra, located in the western part of India, is not in the south-western region. It is known for its large cities like Mumbai and Pune, and its geography includes the Western Ghats and the Konkan coast. Maharashtra is not the state in the south-western part of India.
Tamil Nadu, located in the southern part of India, is not in the south-western region. It is situated to the east of Kerala and is known for its rich cultural heritage and historical sites. Tamil Nadu is bordered by the Bay of Bengal to the east and the Arabian Sea to the west, but it is not the state in the south-western part of India.
Therefore, Kerala is the correct answer as it is the state located in the south-western part of India, distinct from other southern states in terms of its geography, climate, and cultural features.
