Concept:
Urban local government in India is responsible for the administration and development of urban areas such as towns and cities. Different types of local bodies exist depending on the size and population of the urban area.
Step 1: Analyze Statement I.
Municipalities are established in towns to manage local administration, provide civic facilities, and oversee development activities.
Therefore, Statement I is correct.
