Which amendment addresses due process in the U.S. Constitution?

The Fifth Amendment of the U.S. Constitution explicitly addresses due process. It states that no person shall "be deprived of life, liberty, or property, without due process of law." This phrase ensures that individuals are afforded a fair legal process before being deprived of their rights or property, indicating the importance of legal protections in ensuring justice.

While the First and Sixth Amendments also contain important protections regarding individual rights and the legal process, they do not specifically mention due process. The First Amendment primarily focuses on freedoms of speech, religion, and assembly, while the Sixth Amendment guarantees rights related to criminal prosecutions, such as the right to a speedy and public trial, the right to counsel, and the right to confront witnesses.

Thus, the Fifth Amendment is the definitive constitutional provision that directly addresses due process, making it the correct answer.
