Question

which is an example of federal supremacy?
a state is not allowed to tax federal money because federal law is superior.
congress does not have the power to create federal banks.
the supreme court can decide whether a law or act is constitutional.
congress has powers that are not specifically outlined in the constitution.

Explanation:

Federal supremacy means federal law is superior to state law. Option A shows a state being restricted (not taxing federal money) due to federal law's superiority, which fits. Option B is incorrect as Congress can create federal banks (implied by necessary and proper clause). Option C refers to judicial review, not federal supremacy. Option D refers to implied powers, not federal supremacy.

Answer:

A. A state is not allowed to tax federal money because federal law is superior.
