C)cannot be replaced by any safety system.Correct
The seatbelt and the airbag are designed to work in a complementary way. Therefore, if occupants do not use the seatbelt, the inflation of the airbag can even be dangerous. The airbag prevents occupants from directly impacting the various elements of the vehicle. To provide effective protection it is necessary to: - Leave an approximate distance of 25 cm (do not sit close to the steering wheel). - Wear the seatbelt (it is a complement, not a substitute). - Deactivate the passenger airbag if a rear-facing child seat is placed there. - Do not place objects near the airbag or allow the passenger to put their feet on the dashboard.
