Show answer & explanation
Correct answer: B
Explanation
Correct Answer: in custody
Explanation
• The correct idiomatic prepositional phrase is in custody, which means to be kept under arrest or detained by legal authorities.
• The preposition under is incorrectly paired here; legal restraint or arrest by the police is conventionally expressed as being in custody or taken into custody.
• Example: The accused will remain in custody until the next hearing.
