what determines what is local to the router?
no ‘Age’ entry, just a blank
The “Age” field in the “show ip arp” command is the age in minutes of the cache entry. A hyphen (-) means the address is local so in this case 192.168.1.1 & 192.168.3.1 are local to this router -> B is correct.
Note: The “Age 0″ means that the address was cached less than 1 minute ago.
