Identify the statement that would create a default route using a gateway of 192.168.1.1.

netstat is primarily used to display network connections, routing tables, and interface statistics, not to add routes.

The `route` command, specifically with the `add default gw` options, is the correct syntax for adding a default gateway to the routing table. This establishes the path for all traffic destined for networks not explicitly defined in the routing table, directing it to the specified gateway IP address.

The `ip route add default via <gateway_IP>` command is the modern equivalent, but `ip route default` is not the correct syntax for adding a default route with `ip`.

This option is missing the `add` keyword required by the `route` command to establish a new route.

ifconfig is used to configure network interfaces, not to add default routes directly; it's also a deprecated command in favor of `ip`.
