Bonne réponse : B. Reserved lane for buses, taxis, or high-occupancy vehicles

Diamond lanes are reserved for a specific authorised class of vehicle during posted hours — most often buses, taxis, and carpool/HOV vehicles meeting the minimum occupancy. Ordinary single-occupant vehicles using the lane are fined.
