Answer:
The correct answer is option C (UPS).
Step-by-step explanation:
Since brownouts are reduced voltages that might not be good enough for the required electricity capacity for your company, fearing that your computers (especially the servers) could be damaged, it is best to use UPS for your computer protection.
A UPS also called (Uninterruptable Power Supply) can function as a Surge suppressor when the voltages entering your company might be higher than normal, it can also function too in protecting your computers (especially the servers) in the case of a brownout when voltage required by your computers dropped below the required level. In the case of a brownout, the UPS supplies energy stored in its batteries to make the computers keep working without going off from lack of electricity.
