Which bond is designed to ensure Jack's appearance at his trial?

The bond that is specifically designed to ensure a person's appearance at trial is known as a bail bond. In the legal system, bail allows an accused individual to be released from custody before their trial, with the stipulation that they will return to court for the proceedings. The bail bond serves as a financial guarantee provided to the court, ensuring that if the defendant fails to appear, the court can collect the bail amount.

This mechanism provides an incentive for the individual to comply with court dates while allowing them to maintain their freedom prior to the trial. Thus, the bail bond is crucial in the justice system for managing the balance between individual liberties and legal obligations.

In contrast, a performance bond is generally related to the fulfillment of contractual obligations, a fiduciary bond pertains to the responsibilities of someone managing another person's assets, and a commercial bond is typically used in business transactions. None of these types of bonds serve the purpose of securing a defendant's appearance in court as effectively as a bail bond does.
