Explanation: In the context of Indian geography and urban planning, a metro city is a large urban area that serves as a significant economic, political, and cultural center. These cities are characterized by their high population density, extensive infrastructure, and substantial economic activity. The four primary metro cities in India are Delhi, Mumbai, Chennai, and Kolkata.
Delhi, the capital of India, is a major political and economic hub. It is home to numerous government institutions, international organizations, and businesses. Mumbai, often referred to as the financial capital of India, is a major commercial and entertainment center. Chennai, located in the southern part of India, is a significant industrial and cultural center. Kolkata, situated in the eastern part of India, is a major cultural and educational hub, known for its rich literary and artistic heritage.
It is important to note that while there are many large cities in India, not all of them are classified as metro cities. The classification of a city as a metro city is based on its economic significance, population size, and infrastructure. For example, while Bangalore (Bengaluru) is a large and economically important city, it is not traditionally listed among the four primary metro cities.
Understanding the concept of metro cities is crucial for students preparing for competitive examinations such as the UPSC, SSC, and banking exams, as well as state-level PSC exams. These exams often test knowledge of urban geography and the significance of major urban centers in India. The mnemonic "DMCK" (Delhi, Mumbai, Chennai, Kolkata) can be a helpful tool for remembering the four primary metro cities.
In summary, the correct answer to the question is Kolkata, as it is one of the four recognized metro cities in India, alongside Delhi, Mumbai, and Chennai. Students should be familiar with the characteristics and significance of these cities to correctly identify them in questions related to Indian urban geography.
