Correct answer: B. When parking on an unlit road.
When leaving a vehicle on an unlit public road at night this creates a potential danger for other road users. Drivers should therefore leave side/parking lights on, so that the vehicle can be seen by other road users. Drivers should not leave headlights on when parked as this may cause other road users to become disoriented.
