Correct answer: A. A breath sample under 0.02 BAC is required to start the vehicle, plus random retests at unpredictable times once it's running
The driver must blow into the device, mounted near the driver's seat, before the vehicle will start — if their breath-alcohol concentration is over the device's preset fail point of 0.02, the vehicle won't start. Once running, the device also demands random "rolling" retests at unpredictable times, specifically to stop someone else from providing the initial clean sample and then handing over the wheel.
