What is implied by Article IV regarding states’ powers?

Article IV of the U.S. Constitution addresses the relationship between states and the federal government as well as the relationships among states. It establishes that states retain certain powers and can exercise those powers as long as they do not conflict with federal laws. This principle is derived from the Tenth Amendment, which emphasizes that powers not delegated to the federal government are reserved for the states or the people.

The implication of Article IV indicates that states have the authority to legislate on matters that fall within their jurisdiction, provided those matters are not explicitly addressed in federal law. This flexibility allows states to respond to their unique circumstances and needs, illustrating the idea of federalism in which powers are divided between national and state governments.

In contrast, the other suggested answers do not accurately capture the nuance of Article IV. For instance, the assertion that states must follow all federal law without exception overlooks the balance of power and states’ rights emphasized in the Constitution. Similarly, the notion that states have full autonomy without obligation to cooperate contradicts the required cooperation among states as outlined in Article IV, particularly regarding privileges and immunities. Lastly, the idea that states cannot create their own laws misrepresents the states' legislative authority, which is a fundamental aspect of their powers under the Constitution
