Explanation:

A UPS (Uninterruptible Power Supply) provides backup power during outages (like those from thunderstorms) and protects against power surges. A system unit fan cools the computer. A CD - ROM is for reading/writing CDs. A motherboard is the main circuit board. A scanner is for digitizing documents. Since Gary's area has thunderstorms (risk of power issues), a UPS is most useful.

B. UPS
