Answer:
A. Federal
Step-by-step explanation:
A federal state is a political organization in which multiple smaller constituent states voluntarily join together to form a larger political entity. In a federal system, power is divided between the central government and the individual states or regions. The central government typically handles national-level affairs, while the smaller member states retain some degree of autonomy and govern their internal affairs. This arrangement allows for a balance between central authority and regional self-governance.
