Answer: A

Explanation:

Carbon dioxide fire suppression systems need to be combined with an automatic switch to shut down the electricity supply in the event of activation. This is because carbon dioxide displaces oxygen in the air and can create a suffocation hazard for people in the protected area. Therefore, it is essential to cut off the power source before releasing carbon dioxide to avoid electrical shocks and sparks that could ignite the fire again. Carbon dioxide systems are typically used for total flooding applications in spaces that are not habitable, such as server rooms or data centers.
