These cities are characterized by their large populations, high levels of industrial and commercial activity, and administrative importance.
Chennai, located in the southern part of India, is a metropolitan city known for its automobile industry, information technology sector, and cultural significance. It is the capital of Tamil Nadu and has a population of over 4.6 million, making it one of the largest urban centers in South India.
Delhi, the national capital of India, is another metropolitan city. It is a union territory and serves as the seat of the Government of India. Delhi is a major economic hub, with a diverse range of industries and a large population of over 18 million. It is also a significant cultural and historical center, with numerous monuments and museums.

The classification of these cities as metropolitan is based on their population size, economic activities, and administrative roles. Each of these cities plays a crucial role in the economic and cultural landscape of India. Therefore, the correct answer is "All of the above," as all the cities mentioned—Chennai, Delhi, and Kolkata—are indeed metropolitan cities.
Understanding the concept of metropolitan cities is important for comprehending the urban geography and economic dynamics of India. These cities are not only significant in terms of population but also in terms of their contributions to the national economy and their roles in shaping the cultural and political landscape of the country.
