\begin{tabular}{l} According to Article 6 of the United States Constitution, the federal government \\ is the supreme law of the land. It says that U.S. states cannot make laws that go \\ against federal laws. This is an example of: \\ \( \begin{array}{l}\text { O Federalism } \\ \text { O Checks and balances } \\ \text { O Separation of powers } \\ \text { O Rute of law }\end{array} \) \\ \hline\end{tabular}

The scenario described pertains to the **Supremacy Clause** found in Article VI of the United States Constitution. This clause establishes that the federal government holds the highest authority, and its laws take precedence over state laws. Let's break down the options: - **Federalism**: This is the division of power between the national (federal) government and the state governments. The Supremacy Clause is a fundamental aspect of federalism, ensuring that federal laws override conflicting state laws. - **Checks and Balances**: This system ensures that no one branch of government becomes too powerful by allowing each branch to limit the powers of the others. - **Separation of Powers**: This principle divides the government into distinct branches (legislative, executive, judicial) to prevent any one branch from dominating. - **Rule of Law**: This principle states that all individuals and institutions are subject to and accountable under the law. Given that the scenario specifically deals with the hierarchy of federal and state laws, the best answer is: **Answer:** **Federalism**
