Answer:
The Correct Answer is
States must abide by federal law because of the Supremacy Clause
Explanation:
When a state law clashes with federal law, the supremacy article proceeds to nullify the state law in support of the central law one as long as the federal authority is determined to be in following the rules of the Constitution. The supremacy article also suggests that states are not allowed to command, intervene with, or regulate federal issues.
