Answer:
A.) to limit the power of the federal government.
Explanation:
Although the powers of the federal government are limited to those enumerated in the Constitution, those enumerated powers have been interpreted very broadly. And under the supremacy clause of the Constitution, federal law is supreme over state law.
Federalism limits government by creating two sovereign powers—the national government and state governments—thereby restraining the influence of both. Separation of powers imposes internal limits by dividing government against itself, giving different branches separate functions, and forcing them to share power.
