Answer: C

Explanation:

The primary benefit of using a dry-pipe fire-suppression system rather than a wet-pipe system is that a dry-pipe system has a decreased risk of leakage, as the pipes are filled with pressurized air or nitrogen instead of water until the system is activated. A wet-pipe system has a higher risk of leakage, corrosion, and freezing. A dry-pipe system is not more effective at suppressing flames, as it uses the same water-based suppressant as a wet-pipe system. A dry-pipe system does not allow more time to abort release of the suppressant, as it has a delay of only a few seconds before the water is released. A dry-pipe system does not disperse dry chemical suppressants exclusively, as it uses water as the primary suppressant.
