"The arrested persons were produced in court and in remanded judicial custody."

The sentence is discussing the legal proceedings following the arrest of the persons. The first blank requires a word that describes the action of presenting the arrested persons before the court. "Produced" is the best choice here, as it indicates the legal process of presenting the arrested persons before the court.

The second blank requires a word that describes the legal custody in which the arrested persons are being held. "Remanded" is the best choice here, as it refers to the legal custody of an accused person pending trial, usually in prison. The word "remanded" suggests that the accused persons are being held in judicial custody until their trial is completed.
