Which of the following errors does that indicate?

On a Linux workstation, the route command takes a long time before printing out the routing table.

Which of the following errors does that indicate?
A . The local routing information may be corrupted and must be re-validated using a routing protocol.
B . One of the routers in the routing table is not available which causes the automatic router failure detection mechanism (ARF-D) to wait for a timeout.
C . There may accidentally be more than one default router in which case a default router election has to be done on the network in order to choose one router as the default.
D . The Linux Kernel Routing Daemon (LKRD) is not running and should be started using its init script or systemd unit.
E . DNS resolution may not be working as route by default tries to resolve names of routers and destinations and may run into a timeout.

Answer: E
