Which of the following is included in the protections of the Fifth Amendment?

The protection against double jeopardy is included in the Fifth Amendment of the U.S. Constitution, which safeguards individuals from being tried for the same crime twice after a verdict has been reached. This principle is designed to prevent the government from subjecting individuals to multiple prosecutions for the same offense and ensures a finality to legal proceedings, thus protecting citizens' rights and personal liberty.

The other options listed pertain to different amendments: the freedom of speech is protected under the First Amendment, the right to assemble peacefully is also protected by the First Amendment, and the right to petition is covered by the First Amendment as well. Each of these rights serves to enhance individual freedoms but does not fall within the specific protections outlined by the Fifth Amendment, which focuses more on legal procedures and protections during criminal proceedings.
