Which of the following is NOT a form of municipal government in New Jersey?

In New Jersey, the primary forms of municipal government are boroughs, townships, and cities, all of which are types of municipalities that operate under specific governance structures as defined by state law. These municipalities have distinct functions, responsibilities, and community roles recognized by the New Jersey Local Government Code.

Counties, however, are larger administrative divisions that encompass multiple municipalities. They serve as a governmental layer that provides oversight and services such as public health, law enforcement, and infrastructure maintenance across the municipalities within their borders. Counties do not operate as a form of municipal government but rather as an overarching system of local government that coordinates and supports the individual municipalities. Thus, selecting counties as an answer highlights the understanding that it does not represent a municipal form in itself but rather an administrative level above the municipal governments.
