Explanations:The capital city of a state is the primary administrative center where the government of the state is located. It is typically the seat of the state's legislative assembly, the residence of the governor, and the location of major government offices and institutions. In the context of Tamil Nadu, Chennai is the capital city. It is the largest city in the state and serves as the political, economic, and cultural hub.
Chennai, formerly known as Madras, is located on the southeastern coast of India and is the fourth-largest metropolitan area in the country. It is a major commercial and cultural center and is known for its rich cultural heritage, including classical music and dance. The city is also a significant industrial hub, with a strong presence in the automobile, information technology, and healthcare sectors.
Other major cities in Tamil Nadu, such as Coimbatore (often referred to as Covai) and Salem, are important in their own right but are not the capital. Coimbatore is located in the western part of the state and is known for its industrial and educational institutions. Salem, located in the central part of the state, is known for its textiles and educational institutions. However, neither of these cities serves as the administrative center of the state.
Understanding the capital city of a state is important for various reasons, including administrative, economic, and cultural significance. It is a fundamental piece of geographical knowledge that is often tested in competitive examinations and general knowledge quizzes. In the case of Tamil Nadu, Chennai is the correct answer as it is the capital city and the primary administrative center of the state.
