C. Over time, the U.S. system of dual federalism has been replaced with a system of cooperative federalism.

Explanation:

Dual federalism is also known as layer-cake federalism. It´s a political system in which power is distributed between the federal and state governments in precisely specified terms. State governments use that power without obstruction from the federal government.

Cooperative federalism is also known as marble-cake federalism. It´s a system in which national, state and local governments cooperate and collectively address shared problems, instead of creating policies independently.
