The correct answer is A. To determine if there is a probable cause to proceed with trial
Step-by-step explanation:
A preliminary hearing is an important step in criminal justice; this occurs after someone has been accused of committing a crime, and a formal complaint has been filled. During the preliminary hearing, including preliminary hearing in juvenile courts, the judge in charge analyzes whether there is a probable caused to proceed with a trial. This means the judge decides whether there is evidence or reasons that show the person committed the crime and therefore during this stage the process can continue to a trial or end. According to this, the purpose of a preliminary hearing in juvenile court is "to determine if there is a probable cause to proceed with trial".
