The response that best describes how the Alien and Sedition Acts changed the authority of the federal government is:
The acts permitted the government to deny citizens' rights in time of war.
The Alien and Sedition Acts of 1798, enacted by the Federalist-controlled Congress and signed into law by President John Adams, allowed for the deportation of non-citizens deemed dangerous and made it a crime to publish false or malicious criticisms of the government. This legislation significantly expanded the powers of the federal government, enabling it to restrict individual rights, particularly during a time perceived as vulnerable due to foreign threats and domestic dissent.
