French 2023 Q16: Choisissez T’option juste. Il faut……..la loi.

“Il faut respecter la loi” means “One must respect the law.” Respecter is “to respect or obey”.

“Insulter” (to insult) and “gaper” (a misprint, not a real verb here) do not fit. “Aider la loi” (to help the law) is not a normal expression. Only “respecter” makes sense after “il faut”.
