Answer & Explanation
The correct answer is Option B: The heat of the fire melting the link.
Fusible link fire dampers are designed to close automatically when the temperature reaches a certain point. The heat from a fire melts a solder or alloy link, allowing the damper to fall shut and restrict airflow, thus preventing fire and smoke spread.
