Selected Answer: B

It seem a design where the Expressway E is not using a dual nic. So the expressway C can reach to the Expressway-E by hairpining. In these conditions, when you put in query type "all", you are specifying or expecting SRV and A records.Then, it should resolve as A records as SRV records _collab-edge._tls.company.com. But if this is not showings srv's, so it is probably they are missing in the public DNS servers, or may be the records are wrong in the DNS servers or anyway. I think answer is B by my experience.
