I think the first one is correct but i'm not sure about the others. Can someone please help me?

First option is correct. A Surge Suppressor protects when + More than 110 volts.

Explanation:

Sometimes the voltage of the connection quickly increases to a bigger higher value though for a very short period of time. This is called a spike.A surge suppressor is a device inserted in the AC  utility line and telephone line to protect damage to electric devices from voltage spikes. They are a cheap way to protect the electric devices. They gives protection in amounts called joules. A surge suppressor stops the peak AC voltage from going above 110 volts.
