The answer is the third one: Regulator.

Explanation for each option:

  1. Heads up display: This component provides the wearer with information such as air supply levels and other status indicators. It does not control airflow to the wearer.

  2. Air cylinder: This is the component that stores the compressed air. While it is essential for providing the air supply, it does not directly control the airflow to the wearer.

  3. Regulator: This is the correct answer. The regulator is the component that attaches to the SCBA facepiece and directly controls the airflow to the wearer. It reduces the high-pressure air from the cylinder to a breathable pressure and delivers it to the facepiece.

  4. PASS device: The Personal Alert Safety System (PASS) device is a safety feature that emits an alarm if the wearer is motionless for a certain period. It does not control airflow.

In summary, the regulator is the SCBA component responsible for controlling the airflow to the wearer.
