Step 1: Understanding the Question:
The question asks for the general minimum population threshold for a city to have a Municipal Corporation (Nagar Nigam).
Step 2: Key Concept:
The 74th Constitutional Amendment Act provides for a three-tier system of urban local bodies: Nagar Panchayat (for a transitional area), Municipal Council (for a smaller urban area), and Municipal Corporation (for a larger urban area). However, the specific criteria, including population, for constituting these bodies are determined by the respective state legislatures.
Step 3: Detailed Explanation:
Since the criteria are defined by state laws, there is no single uniform population figure applicable across all of India. The population requirement varies from state to state.
- In some states, the minimum population required for a municipal corporation might be as low as 1 lakh or 3 lakhs.
- In other states, particularly larger ones, the threshold is higher, often set at 5 lakhs or even 10 lakhs.
- For example, the Uttar Pradesh Municipal Corporation Act, 1959, generally provides for a corporation in a city having a population of five lakhs or more.
Given the options, and considering the general practice in many states, a population of "More than 5 lacs" is a common and reasonable threshold for establishing a Municipal Corporation, representing a 'larger urban area'. The marked answer in the source image also indicates (C).
Step 4: Final Answer
While the specific population criteria vary by state, a common threshold for the creation of a municipal corporation is a population of more than 5 lakhs.
