Answer:
Option B, commissioner, is the right answer.
Step-by-step explanation:
In the United States, the oldest form of county government is the board of Commissioner. This form of government was prevalent in the south during the colonial rule as the south was densely populated.
The elected commissioners in such form of government serve both the executive and the legislative offices. They may enact local rules and may govern them. The main responsibility or job of the county commissioners is to approve budgets and oversee the spending and hiring of the county employees.
