What is included in the setup of a witness during a trial?

The setup of a witness during a trial primarily involves the procedures related to calling the witness to the stand and administering their oath. This process is essential as it establishes the witness's credibility and the requirement for them to tell the truth under penalty of law. The calling of a witness includes formally introducing them to the court and often involves the attorney outlining the witness's qualifications, relevance, and what they will testify about. Administering the oath is a critical step that legally binds the witness to provide honest testimony, setting the stage for the evidence they will present.

The other options do not pertain directly to the initial setup of a witness. Final summation comments come after all testimony has been heard and are part of the closing arguments, while the testimony of the defendant is a separate procedure that occurs later in the trial. The appeal process follows the conclusion of the trial and is not part of the witness setup.
