A zone file contains the following lines:

$ORIGIN example.com
host2.example.org. IN A

and is included in the BIND configuration using this configuration stanza:

zone "example.com" {
     type master;
     file "db.example.com";

Which problem is contained in this configuration?

A. The zone statement is the BIND configuration must contain the cross-zone-data yes; statement.
B. The zone cannon contain records for a name which is outside the zone's hierarchy.
C. The $ORIGIN declaration cannot be used in zone files that are included for a specific zone name in the BIND configuration.
D. An A record cannot contain an IPv4 address because its value is supposed to be a reverse DNS name.
E. Names of records in a zone file cannot be fully qualified domain names.
