Explanation: Tamil Nadu is a state located in the southernmost part of the Indian subcontinent. It is one of the four southern states of India, along with Kerala, Karnataka, and Andhra Pradesh. Tamil Nadu is bordered by the Bay of Bengal on the east, the Arabian Sea on the west, and the Indian Ocean on the south. The state is known for its rich cultural heritage, historical sites, and diverse geography, including the Western Ghats, the Eastern Ghats, and the Coromandel Coast.
The term "southernmost" refers to the state that is located at the southern tip of the Indian subcontinent. Tamil Nadu is the southernmost state because it is situated at the southernmost point of the Indian peninsula, extending to the Indian Ocean. The southernmost point of the Indian subcontinent is located at Kanyakumari, a town in Tamil Nadu, which is also known as the "Land's End" of India.
It is important to understand the geographical layout of the Indian subcontinent to correctly identify the southernmost state. The Indian subcontinent is a peninsula that extends into the Indian Ocean, with the Bay of Bengal to the east and the Arabian Sea to the west. The southernmost part of this peninsula is occupied by Tamil Nadu, making it the southernmost state in India.
Other states like Jammu & Kashmir, which is located in the northern part of India, and New Delhi, which is the capital city of India and located in the northern part of the country, are not the southernmost locations. Therefore, the correct answer is Tamil Nadu, as it is the state that lies furthest south in India.
