Final answer:
Dual Federalism advocates a strong separation of federal and state/local governments, while Cooperative Federalism involves the cooperation and blending of functions between them.
Step-by-step explanation:
The correct answer is d. Dual Federalism. Dual federalism advocates a strong separation of federal and state/local governments that generally work independently of one another. This concept views the relationship between the federal government and the state governments as separate and distinct, resembling a layer cake. In contrast, cooperative federalism, also known as marble cake federalism, involves the cooperation and blending of functions between the federal and state governments.
