If the proper office does not demand the arrested person within how many days, must the person be discharged?

The correct answer is based on the provisions within the Texas Code of Criminal Procedure concerning the timeline for an arrested individual's demand for a hearing. If the proper office, such as the district attorney or prosecuting agency, does not demand the arrested person for trial within 11 days, the individual must be discharged from custody. This requirement ensures that an arrested individual is not held indefinitely without proper legal proceedings and offers a safeguard for the accused, promoting timely justice and adherence to due process.

Understanding this provision is crucial, as it emphasizes the importance of ensuring that legal actions are taken promptly after an arrest, thereby protecting the rights of individuals within the criminal justice system.
