Explanation: Tamil Nadu is a state located in the southern part of India, and it is part of the Southern Plateau. The Southern Plateau, also known as the Deccan Plateau, is a large elevated region in the southern part of the Indian subcontinent. This plateau is characterized by its high elevation and distinct geological features, which make it a significant geographical region in India.
Regarding rainfall, Tamil Nadu experiences a monsoon climate with two main seasons: the southwest monsoon and the northeast monsoon. The southwest monsoon typically affects the western coast of India, bringing rain to states like Kerala and Karnataka. However, Tamil Nadu receives its major rainfall during the northeast monsoon, which occurs from October to December. This monsoon is crucial for agriculture in Tamil Nadu, particularly for the cultivation of crops like paddy and sugarcane.
The third statement pertains to the Tamil language, which is one of the oldest classical languages in the world. Tamil has a rich literary tradition dating back over 2,000 years, with a vast corpus of literature that includes poetry, prose, and drama. The language is recognized as a classical language by the Government of India, based on its ancient heritage, literary tradition, and historical significance. Tamil is spoken by millions of people in Tamil Nadu and is also widely used in other parts of the world, particularly in Sri Lanka, Singapore, and Malaysia.
In summary, the correct answer is (D) Only 1, 3. Tamil Nadu is indeed part of the Southern Plateau, and Tamil is one of the oldest classical languages in the world. The second statement is incorrect because Tamil Nadu's significant rainfall occurs during the northeast monsoon, not July to September. Understanding these geographical and cultural aspects of Tamil Nadu is crucial for comprehending the state's unique characteristics and its place in the broader context of Indian geography and culture.
