Which statement best describes fire suppression systems as mentioned in the material?

• A. Fire suppression systems using water to extinguish fires.
• B. Fire suppression systems using foam to extinguish fires.
• C. Fire suppression systems that only monitor for fires.
• D. Fire suppression systems relying on halogenated compounds.

Answer: (A)

In NFPA 13R for low‑rise residences, fire suppression is about water-based systems that automatically release water through sprinklers when heat is detected, to cool and control the fire and protect occupants. Foam systems aren’t the standard for homes, and systems that only monitor for fires describe detection without discharge. Halogenated clean-agent systems exist in some applications but aren’t the typical method described for residential sprinkler protection. So the best description is fire suppression systems using water to extinguish fires.
