- A. Correct.
This is the correct command to configure the router as an NTP client, allowing it to synchronize with the authoritative NTP server at 192.168.1.1.

This command sets the device as an NTP master, which makes it an authoritative time source rather than a client. This is not the correct configuration for the described scenario.
