The correct response is:
Federal laws must be consistent with the language and powers granted in the U.S. Constitution.
This option accurately reflects the principle of constitutional supremacy in the United States, where the Constitution is the supreme law of the land. All federal laws must align with the Constitution's provisions, ensuring that any law enacted by Congress or by federal authorities complies with the powers and limitations outlined within the document. This serves as a foundational aspect of the legal system in the U.S., guiding courts in their interpretations of federal law.
