Concept:In a confederal system, the component states or regions retain ultimate authority and sovereignty.
Explanation:Under a confederal system, the central government exercises only the powers given to it by the component units.
Each component unit remains independent and sovereign, with the central body acting as their agent.
In a federal system, sovereignty is divided between the central government and component units, so neither is fully sovereign.
In a monarchical system, the monarch holds supreme power, and component units are not sovereign.
In a republican system, sovereignty lies with the people, not with individual component units.
Therefore, the correct option is Confederal.
Answer:A. Confederal
