Given the following /etc/named.conf DNS server configuration file:

zone "one.edu" in {
type master;
file "forward.zone";
allow-update { 127.0.0.1; 192.168.1.2; };
};
zone "1.168.192.in-addr.arpa" in {
type master;
file "reverse.rzone";
allow-update { 127.0.0.1; 192.168.1.2; };
};

In which way does the allow-update option change the behavior of the primary DNS server?

A.
The DNS server dynamically updates forward DNS servers.

B.
The DNS server dynamically updates reverse DNS servers.

C.
The DNS server dynamically updates secondary DNS servers.

D.
The DNS server can be dynamically updated by root DNS servers.

E.
