Under Texas law, one of the statutes that deals with the rights of inmates is titled:

The correct answer is the title commonly recognized in legislation as the "Inmate's Bill of Rights." This statute specifically outlines the rights entitled to inmates in correctional facilities in Texas. It aims to protect the basic rights and humane treatment of individuals who are incarcerated, ensuring they have access to necessary services, like healthcare, opportunities for education, and are treated fairly.

The terminology "Due course of the law" often refers to the broader legal principle found in the Texas Constitution, which guarantees fair procedures but is not specifically focused on inmates' rights. Other options presented, such as "Due process of law" and "Rights of the incarcerated," may seem relevant, but they do not precisely correspond to the specific title of Texas law addressing the rights of those in jails or prisons. The "Inmate's Bill of Rights" is the definitive reference that encompasses these protections and regulations pertinent to incarcerated individuals.
