Concept:A confederal system has a weak central government and strong component units.
Explanation:In a confederal system, the component states or regions are sovereign.
They surrender only limited powers to the central government.
This makes the power of the component units greater than that of the central government.
The central government depends on the component units for its existence.
It can only act with the consent of those units.
Important features include strong component units, a weak centre, freedom of secession, and citizens' loyalty to their own unit.
The central government relates mainly to the member units, not to individuals directly.
This differs from a federal system, where power is shared, and a unitary system, where the central government is supreme.
Answer:D. Confederal.
