What agency operates facilities for the detention of juveniles?

The correct answer highlights the role of specialized agencies that focus on the welfare and rehabilitation of youth. The Office of Juvenile Justice is the appropriate entity that specifically addresses the needs and issues surrounding juvenile detention facilities. This office is dedicated to overseeing programs and policies related to juvenile justice, ensuring that juveniles are treated in ways that are developmentally appropriate and aligned with their rehabilitation needs.

This answer reflects an understanding of the juvenile justice system and the emphasis on rehabilitation rather than punishment, which is a cornerstone of juvenile law. In contrast, agencies like the Department of Justice and the Department of Corrections typically deal with adult offenders and may not specialize in juvenile matters, while a child welfare agency primarily focuses on the overall welfare and protection of children, rather than the specifics of juvenile detention facilities.
