Several U.S. southern states pass a law that restricts the sale of alcohol by businesses on Sunday between the hours of 6AM and midnight. A few weeks later, the federal government passes a law that says "no jurisdiction shall restrict the sale of alcohol in any manner." Would the states still be permitted to restrict sales of alcohol within their borders? a. No, because the federal law was passed after the state laws. b. Yes, because the federal law is only valid in federal territory (Washington, DC). c. Yes, because the federal law was passed after the state laws. d. No, because federal law preempts state law.
