Which of the following is true regarding peremptory challenges?

Peremptory challenges are a tool used in jury selection that allows attorneys to reject certain jurors without needing to provide a reason or justification. This is a key aspect of how peremptory challenges function, as it grants attorneys the discretion to remove jurors based on instinct or strategic considerations regarding how a juror may influence the trial, without the requirement of articulating those reasons in court.

The ability to use these challenges without justification helps maintain an element of flexibility in jury selection, allowing attorneys to create a jury they believe will be most favorable to their case. This contrasts with challenges for cause, where a specific reason must be provided, such as a potential juror's bias or conflict of interest.

In addition to this fundamental characteristic, it is also important to understand the limitations surrounding peremptory challenges, such as that they are not unlimited in number and that their use is applicable in both civil and criminal cases, not restricted solely to criminal proceedings.
