Explanations:The concept of a metropolitan city in India is defined by its population and the extent of its urban area. A metropolitan city typically includes the main city along with its surrounding urban areas, which are often interconnected through transportation and economic activities. The largest metropolitan city in India is determined by these factors, and among the options provided, Delhi stands out as the largest metropolitan city.
Delhi, the national capital of India, has a significant population and a vast urban area. The city is home to millions of people and has a sprawling urban landscape that extends beyond the city limits. The urban area of Delhi includes several satellite towns and neighboring regions, making it the largest metropolitan city in the country. The population of Delhi is also one of the highest in India, contributing to its status as the largest metropolitan city.
Other major cities like Kolkata and Chennai are significant in their own right, but they do not match the scale of Delhi in terms of population and urban area. Kolkata, for example, is a major city in eastern India with a large population, but it does not have the extensive urban sprawl that Delhi has. Similarly, Chennai, located in southern India, is a major metropolitan city but is smaller in comparison to Delhi.
It is important to note that the size of a metropolitan city is not solely determined by its population but also by the extent of its urban area. This includes the interconnectedness of the city with its surrounding regions, the infrastructure, and the economic activities that extend beyond the city limits. In this context, Delhi stands out as the largest metropolitan city in India, making it the correct answer to the question.
