This question is weird. Let's go: if IS-IS is working then L2 is too, and this is important to resolve this issue. If the issue was a connection problem, checking RIB and then debug ARP would be an option in case the operator got the network misconfiguration. But I think the question would be: ARP does not appear ("ARP entry has not yet been created"). How to make ARP appear? In this case maybe C is the best option
