NAC stands for ___.

Explanation:
NAC stands for Notification Appliance Circuit—the part of a fire alarm system that powers and signals the notification devices (horns, bells, strobes) so occupants are alerted. It is a dedicated, power-limited circuit designed specifically to supply the current needed for those devices. The other options don’t fit fire-alarm terminology: it isn’t a generic nominal alternating current, nor a term like non-addressable class, and it isn’t a safety term like non-arcing conductor.
