Answer:
The Fifth Amendment
Explanation:
Double jeopardy refers to punishing the same person twice for almost same crime or any act which is punishable.
Accordingly, in the fifth amendment there is a clause which clearly states that no person shall be prisoner for same offence for same period for same act.
As once a person is punished for an offence, clearly he shall not be punished again for the same act. This provides benefit to the prisoner, whether criminal act or other kind.
Thus, correct answer is fifth amendment.
