Answer:D) The power of the national government is increased, and the power of the states is reduced.
Explanation:D) The Supremacy Clause establishes that federal law is the supreme law of the land, overriding conflicting state laws. Supreme Court rulings, such as those mentioned in the table, have consistently upheld the principle that federal law takes precedence over state laws in cases of conflict. This reinforces the authority of the national government and limits the power of individual states in areas where federal laws apply.
