Which of the following areas does not have a reasonable expectation of privacy?

Prison cells do not have a reasonable expectation of privacy primarily because inmates are under the supervision of corrections officers and the facility has a vested interest in maintaining security and order. The legal framework surrounding prisons allows for searches and surveillance that would typically violate individual privacy rights outside of that context.

In contrast, private residences, hotel rooms, and workplaces generally afford individuals a higher expectation of privacy. Residents in private homes and hotel guests expect a certain level of confidentiality and personal space. Similarly, in workplaces, there are established privacy rights, although these can vary based on company policies and the nature of the job. In the context of prisons, the diminished rights result from the nature of incarceration and the necessity to ensure safety and compliance with regulations within a controlled environment.
