Refer to the exhibit. Which route will be found in the routing table of the Main router?

A route code of 'C' denotes a directly connected interface, which is assigned by the operating system automatically and cannot be a route received from a neighboring router via RIP.

The /24 mask on 192.168.2.0 does not match the subnet mask assigned to that segment in the exhibit, so this entry would not appear in the routing table as shown.

The entry 'R 192.168.255.16 [120/1] via 192.168.255.26, 00:00:24, Serial0/0' correctly identifies a RIP-learned route with administrative distance 120 and a metric of 1, meaning the destination subnet is exactly one hop away via Serial0/0. The next-hop address 192.168.255.26 and the subnet 192.168.255.16 correspond to the addressing visible in the exhibit, making this the only entry that correctly reflects topology and RIP behavior.

A metric of 2 in '[120/2]' would mean the destination is two hops away, but the exhibit topology places the relevant subnet only one hop from the Main router, so metric 1 is correct.
