On a DHCP client, the interface is down and configured with the IP address
0.0.0.0. After typing ifconfig hme0 dhcp start, you observe snoop output that does not include a
DHCPDISCOVER packet :

OLD-BROADCAST -> BROADCAST DHCP/BOOTP DHCPREQUEST
192.168.10.1 -> 192.168.10.10 DHCP/BOOTP DHCPACK

Which command was used to shut down the interface in such a way that a DHCPDISCOVER was NOT required?

A.
dhcpagent -r hme0

B.
dhcpconfig -r hme0

C.
ifconfig hme0 dhcp drop

D.
ifconfig hme0 dhcp release
