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 prohibits states from denying any person the right to "life, liberty, or property, without due process of law." This amendment was adopted in 1868 and is a crucial aspect of the constitutional protection of individual rights, reinforcing the principle of due process at the state level, which was initially established by the Fifth Amendment applicable at the federal level.

The concept of due process is fundamental within the U.S. legal system, ensuring that all individuals receive fair treatment through the judicial system. This amendment not only secures individual rights but also limits the power of the government in its dealings with citizens, making it a cornerstone of American civil rights.

Other options pertain to different rights: the Fourth Amendment focuses on protection against unreasonable searches and seizures, the Sixth Amendment guarantees rights related to criminal prosecutions (like the right to a fair trial), and the Eighth Amendment addresses prohibitions against cruel and unusual punishment. Each of these amendments serves an important role but does not encompass the specific guarantee of due process as articulated in the Fourteenth Amendment.
