What must an individual post to be released from jail?

To be released from jail, an individual typically must post bail or a bond. Bail serves as a monetary guarantee that the individual will return for their scheduled court appearances. The amount of bail is usually set by a judge and can vary based on the severity of the charges, the individual's criminal history, and other factors that might impact flight risk or public safety. A bond, which often involves a bonding company, allows individuals who cannot afford the full bail amount to secure their release by paying a percentage of the total amount, usually non-refundable.

The other options do not directly pertain to the procedure for release from jail. An admission of guilt is related to the legal process that follows a charge but does not facilitate release on its own. An indictment is a formal accusation that begins a criminal case but occurs after arrest and does not determine release conditions. A preliminary hearing is part of the legal process to determine if there is enough evidence to proceed with charges, but it does not directly relate to immediate release from custody.
