Which term denotes the state's guardianship role for youths?

• A. Habeas corpus
• B. Stare decisis
• C. Parens patriae
• D. Ex post facto

Answer: (C)

The main concept tested is the state's guardianship role for youths, which is captured by parens patriae. Parens patriae is a Latin term meaning “father of the country” and describes the government's authority to protect those who cannot protect themselves, especially minors. This power underpins how courts and child welfare agencies intervene in situations involving children—placing a child in protective custody, removing them from unsafe homes, or providing welfare services when a minor’s welfare is at risk.

That’s why this term is the best fit: it directly reflects the state’s duty to act as guardian for youths. The other terms describe different legal ideas: habeas corpus concerns protection against unlawful detention, stare decisis involves following precedent, and ex post facto refers to laws that retroactively change the legal consequences of actions. None of those describe the protective, guardianship role of the state toward minors in the way parens patriae does.
