What must the budget summary publication include regarding the principal municipal building?

The correct choice emphasizes the importance of providing clear and accessible information about the principal municipal building, which serves as a central point for residents to interact with their local government. Including the location, phone number, office hours, and a designated name for mail requests ensures that citizens can easily find and contact the municipality when they have inquiries or need assistance regarding budget matters or other local services.

This information supports transparency and accountability in the municipal budget process, allowing residents to engage more effectively with their government. By having these contact details readily available, the municipality fosters open communication and encourages public participation, which is vital in the budget process. In contrast, simply listing the name of the municipality or the names of officers does not provide the necessary functional details for residents to navigate municipal services effectively. A summary of budget content is also important, but it does not directly support the operational accessibility that the principal building information provides.
