Which amendment ensures that no person can be denied life, liberty, or property without due process?

The Fourteenth Amendment is the correct answer because it explicitly states that no state shall deny any person the equal protection of the laws or the right to due process of law. The concept of due process is critical in safeguarding individuals from arbitrary denial of life, liberty, or property by the state. This amendment extends the protections of the Bill of Rights, particularly those related to due process, to actions taken by state governments, establishing that individuals have a fundamental right to fair treatment through the normal judicial system.

The other amendments listed do not address the concept of due process in this context. The Fourth Amendment primarily deals with protection against unreasonable searches and seizures. The Sixth Amendment guarantees specific rights related to criminal prosecutions, such as the right to a speedy trial and the right to counsel. The Eighth Amendment addresses protection against excessive bail, fines, and cruel and unusual punishments. Therefore, the Fourteenth Amendment is the only option that directly enshrines the principle of due process in relation to life, liberty, or property.
