Which statement best describes the service disconnect?

Explanation:
The service disconnect is the main shutoff that can completely isolate the building from the utility supply, used for safety during maintenance or emergencies. It doesn’t change the waveform (that would be a rectifier), meter energy (that’s done by the electrical meter), or boost voltage (that would be a transformer or regulator). So the best description is that it isolates the building from the utility during maintenance.
