The correct answer is 1.
The Fifth Amendment to the US Constitution was passed in 1971 as part of the Bill of Rights, aiming to regulate criminal processes. It is applicable to every public administration office (at the federal, state or local levels), enterprise, association or individual in the United States.
Among other provisions, it contains the Double Jeopardy Clause, which states that defendants can be tried just once in a federal court for the same crime.
