Which group typically comprises a Petit Jury?

A Petit Jury, also known as a trial jury, typically consists of 12 persons who are selected to hear evidence in a court case and determine the verdict. Their primary role is to listen to both sides of the argument, evaluate the evidence presented, and make a decision regarding the guilt or innocence of the defendant in criminal cases, or liability in civil cases.

This structure of having 12 jurors is rooted in historical legal traditions, as a diverse group helps ensure that multiple viewpoints are considered. Jurors' deliberations help provide a check on the legal system, as the decision must typically meet a consensus among a significant number of the jurors. Smaller juries can lead to different dynamics and outcomes, which is why this specific arrangement is favored in many legal systems.

In contrast, other answer choices do not align with the traditional definition of a Petit Jury. For instance, a group of 10 people does not meet the standard size commonly used in juries, while a panel of judges or law enforcement members would not serve in the capacity of a jury in a trial context.
