Answer:
(Choice C) National policymaking is held in check.

Federalism is the constitutional policy of the division of power between the federal and state governments. This division of power signifies the equalization of power for the different levels of authority.
One of the consequences of federalism in the United States is that the national policy-making is held in check. This is because federalism presents a limit to the power of the different levels of the governing bodies.
Thus, the correct answer is option C.
