A) true

The purpose of antilock brake systems is to prevent the brakes from becoming locked by sensing if they are locked and then automatically releasing them and applying pressure. If you don't have antilock brakes, you can avoid your brakes locking up by manually and rapidly releasing and reapplying pressure to your brake pedal ("pumping the brakes").
