Someone here will be happy to check on what YOU WRITE. No one will write your assignment for you, though.

It's not an assignment.

Wouldn't it be the power was divided between The states ad national government?

Yes

By the way a principal is not a principle.

The statement that best illustrates the principle of federalism is: "In a federal system, power is divided between a central government and regional governments, allowing each level of government to have its own authority and responsibilities."

Explanation: To understand the principle of federalism, we need to have a basic understanding of how it works. Federalism is a system of government in which power is shared between a central authority and regional or state governments. This division of power is key to the concept of federalism. In a federal system, the central government has certain powers and responsibilities, while the regional or state governments have their own set of powers and responsibilities. This distribution of power promotes the idea of dual sovereignty, where both the central and regional governments have the ability to make decisions and govern in their respective areas.
