Which of the following is a key right protected by the Due Process Clause?

The Due Process Clause, found in the Fifth and Fourteenth Amendments of the U.S. Constitution, is primarily concerned with ensuring fairness in legal proceedings and protecting individuals from arbitrary denial of life, liberty, or property. The right to a fair trial is directly linked to the principles of due process, as it guarantees that individuals are afforded a proper judicial process, including the right to be heard, the right to an attorney, and the right to an impartial jury. These protections are fundamental in maintaining the integrity of the legal system and ensuring that justice is administered fairly.

While other rights listed, such as the right to vote, the right to free speech, and the right to privacy, are indeed significant constitutional rights, they are primarily protected under different clauses. The right to vote is protected by various amendments and laws focused on electoral processes, the right to free speech is safeguarded by the First Amendment, and the right to privacy is derived from various constitutional protections interpreted by the courts. However, the right to a fair trial directly embodies the core principles of due process, making it a fundamental key right specifically protected under the Due Process Clause.
