Which hearing is concerned with oral, physical, and identification evidence?

The correct answer is C, the 3.6 hearing, which is specifically focused on the admissibility of oral, physical, and identification evidence. This type of hearing is crucial in the legal process because it allows the court to determine what types of evidence can be presented during a trial.

In a 3.6 hearing, the prosecution must demonstrate that the evidence meets certain legal standards, ensuring that only relevant and reliable information is considered in court. This safeguards the integrity of the judicial process and protects the rights of the accused by ensuring that evidence is not only pertinent but also gathered and presented in a lawful manner.

The other choices relate to different types of legal hearings that do not specifically focus on evidence; for example, a 3.1 hearing usually addresses the competency of a defendant to stand trial, while a 3.5 hearing pertains to the voluntariness of confessions. Understanding the distinctions and purposes of these different hearings is essential for legal professionals when navigating the judicial system.
