A Linux computer has no access to the internet. Which command displays information about the network gateway for the system?

traceroute probes the path to a remote host by sending packets across the network; it requires internet connectivity and does not simply display local routing configuration.

ifconfig displays and configures network interface parameters such as IP address and MAC address, but does not show routing table or gateway information.

gateway is not a standard Linux command; no such utility exists in typical Linux distributions.

The route command reads the kernel routing table and displays all configured routes, including the default gateway shown as the 0.0.0.0 destination entry with the gateway IP in the Gateway column. It functions entirely from local kernel data and requires no internet access, making it the correct tool for inspecting gateway configuration offline.

ipconfig is a Windows command-line tool and does not exist in Linux; the Linux equivalent for interface info is ifconfig or ip addr.
