I think, the correct answer should be B. To delegate domain DNS management to Azure DNS management, NS record should be registered at domain registrar's DNS management, not at Azure DNS management.

Right - a NS record would be created automatically and you cannot modify it (but you can add to it to support co-hosting domains). see: "You can add additional name servers to this NS record set, to support co-hosting domains with more than one DNS provider. You can also modify the TTL and metadata for this record set. However, you cannot remove or modify the pre-populated Azure DNS name servers." https://docs.microsoft.com/en-us/azure/dns/dns-operations-recordsets-portal#work-with-ns-and-soa-records
