Which of the following is not a procedural defense but can be used to prove one’s innocence? Entrapment
Double jeopardy
Alibi
Prosecutorial misconduct

I am leaning towards "Alibi". This suggests that the defendant was somewhere else when the alleged crime occurred.

Explanation:

Entrapment is the coercion of Police Departments to try and frame someone of a crime.

Double Jeopardy relates to the U.S. Constitution and prohibits someone from being convicted more than once of the same crime.

Prosecutorial misconduct is a way in which the prosecutor interferes with due process. Some examples are -- getting the news to sway the public (creating bias). Perjury (not telling the truth), and finally, tampering with the evidence.

Therefore, I think it is the "Alibi". C.
