The correct answer is: A. an ex post facto law.

An ex post facto law is one that makes an action illegal retroactively, meaning that it punishes someone for an act that was not considered a crime when it was committed. This type of law is prohibited by the U.S. Constitution because it violates the principle of fairness in the legal system.
