D. For each zone, select Scavenge stale resource records. E. From the Advanced settings of the DNS server properties, select Enable automatic scavenging of state records. It is similar to the question 44.

I think the given answer D and E are correct. Following text(*1) says that to enable scavenging, you must enable it on both the DNS zone(s) and on the server(s) that host those zones. Because of this D and E are correct. A and C are just settings which can't delete records.

About C SOA is to DNS zone, not for DNS records.
