Explanations:In India, the local governance system is divided into rural and urban areas. Rural areas are governed by Gram Panchayats, which are village-level self-governance bodies. Urban areas, on the other hand, are governed by different types of bodies depending on the size and population of the city. The primary urban local governance bodies are Municipal Corporations and Municipal Committees.
Municipal Corporations are the highest level of urban local governance in India. They are responsible for the administration of large cities with a population of more than one million. These corporations are elected bodies that manage civic services, infrastructure, and public utilities in metropolitan areas. They have a more complex structure compared to Municipal Committees, with a larger number of elected members and a more extensive range of responsibilities.
Municipal Committees, on the other hand, are smaller in scale and manage smaller urban areas. They are responsible for the administration of towns and smaller cities with a population of less than one million. These committees have a simpler structure and fewer responsibilities compared to Municipal Corporations.
Gram Panchayats are rural governance bodies and are not applicable to urban areas. They are responsible for the administration of villages and rural areas, managing local development and welfare programs.
In the context of the question, Mumbai, Kolkata, Chennai, and Delhi are all major metropolitan cities with populations exceeding one million. Therefore, they are governed by Municipal Corporations, which are the appropriate local governance bodies for such large urban areas. These corporations manage the civic services, infrastructure, and public utilities in these major cities, ensuring the smooth functioning of urban life.
