Which of the following is an example of a special district?

A fire district is indeed an example of a special district because it is an independent governmental entity that is established to provide fire protection services within a specific geographical area. Special districts are created by municipalities or counties to address a particular need, such as fire protection, and operate independently from the general municipal government. This allows for focused management of resources and funding for specific services.

The other choices provided represent different types of governmental functions but do not fit the definition of a special district. The police department and public works department are typically part of the larger municipal government structure and provide essential services as departments rather than as separate entities. A municipal library, while often established to meet community needs, usually functions under the municipal or county government rather than as an independent special district. Therefore, the operation and funding mechanisms of a fire district distinguish it as a special district in New Jersey.
