Answer:
The correct answer is "B - Confederation."
In a confederation system of government, the state or local government is the final authority. This means that each state or local government has more power than the central government, and can make decisions independently without interference from the central government.
Advantages of a confederation system include local governments having more control over their own affairs and being able to address local issues more effectively. Disadvantages may include a lack of unity and coordination across the entire country, as well as the possibility of some state or local governments becoming too powerful and dominant.
The other options are incorrect because in a unitary system, the central government has the final authority; in a federal system, power is shared between the central government and state/local governments; and in a monarchy, the monarch is the final authority.
