I'm not sure, but I think C) Custom channel could also be a possibility.

Custom channel? Sounds like the malware author was trying to be a special snowflake. I'll go with B, Dnscat2, it's the most technical-sounding one.

Dnscat2? Sounds like a dance move to me! But hey, at least it's not FTP - that's so 90s.
