Final answer:
The correct option is d. France has a unitary government, where the central government in Paris holds most of the power and the regional governments only exercise the powers delegated by the national government.
Step-by-step explanation:
France has a unitary government. In a unitary system, the central government holds most of the power and local and regional government offices are under the control of the central government. This means that the national government in Paris is supreme and the regional governments, such as the régions, départements, and communes, only exercise powers delegated by the national government.
This type of government is different from a federal government, in which power is divided between the central government and regional governments, and a confederal government, in which power is held primarily by the regional governments.
