Explanation: In the context of Indian geography and urban planning, a metro city is a term used to describe a large urban area that plays a significant role in the country's economic, political, and cultural landscape. These cities are characterized by their high population density, advanced infrastructure, and substantial influence on national and international affairs.
Delhi and Mumbai are two of the most prominent metro cities in India. Delhi, the capital of India, is a hub for government, politics, and international diplomacy. It is also a major economic center with a diverse range of industries and a well-developed transportation network, including the Delhi Metro, which is one of the largest metro systems in the world. Mumbai, on the other hand, is known as the financial capital of India and is a major center for commerce, entertainment, and industry. It is home to the Bombay Stock Exchange and has a significant presence in the film industry, often referred to as Bollywood.
Nashik, while an important city in the state of Maharashtra, does not meet the criteria to be classified as a metro city. It is a significant industrial and educational center, but it lacks the extensive infrastructure and economic influence that characterize metro cities like Delhi and Mumbai.
The classification of metro cities is important for urban planning, resource allocation, and policy-making. These cities often receive special attention in terms of infrastructure development, public services, and economic policies. Understanding the distinction between metro cities and other urban areas is crucial for students of geography, urban planning, and those preparing for competitive examinations that cover Indian general knowledge.
In summary, the correct answer is (D) Only (A) & (B), as Delhi and Mumbai are recognized as metro cities, while Nashik is not. This distinction is based on the significant economic, political, and cultural roles these cities play in India, as well as their advanced infrastructure and population density.
