Question

what is the advantage of a surge protector over a power strip?
it stops electricity spikes.
you can plug in more devices.
it prevents malicious software attacks.
it costs less.

Explanation:

A surge protector's main function is to protect electrical devices from voltage spikes (surges) in the electrical supply. A power strip mainly provides multiple outlets but doesn't protect against surges. Plugging in more devices is a feature of power strips too, not a surge protector advantage. Surge protectors don't prevent malware (that's for security software) and usually cost more than basic power strips. So the correct option is the one about stopping electricity spikes.

Answer:

A. It stops electricity spikes.
