Explanations:To understand the geographical layout of southern India, it is important to recognize the relative positions of the states. Tamil Nadu is located in the southernmost part of the Indian peninsula, bordering the Bay of Bengal to the east and the Arabian Sea to the west. Maharashtra, on the other hand, is located in the western part of India, bordering the Arabian Sea to the west and the states of Karnataka and Telangana to the south.
When traveling from Tamil Nadu to Maharashtra, the most direct route involves crossing the state of Karnataka. Karnataka is situated between Tamil Nadu and Maharashtra, forming a natural corridor between these two states. The state of Karnataka is known for its diverse geography, including the Western Ghats, the Deccan Plateau, and the coastal plains along the Arabian Sea.
Other states in the region, such as Kerala and Andhra Pradesh, do not lie directly on the route from Tamil Nadu to Maharashtra. Kerala is located to the west of Tamil Nadu, bordering the Arabian Sea, and does not form a direct path to Maharashtra. Andhra Pradesh is located to the northeast of Tamil Nadu and is not directly on the route to Maharashtra.
Therefore, the correct answer is Karnataka, as it is the state that must be crossed to travel from Tamil Nadu to Maharashtra. Understanding the geographical layout of Indian states is crucial for various competitive examinations and general knowledge assessments, particularly those related to geography and regional studies.
