County governments are established as outlined by a state's constitution.

Option (D) is correct

Explanation:

The county government is the local government. The County government is governed by the board of county commissioners elected by the citizens of a country. These commissioners are elected for a term of four years. The county government performs various functions such as registering voters, looking after health and welfare and maintaining records, etc.

The authority of the county government is limited by state so these governments are established and controlled by the state's constitution.
