I have a question about subnetting:

I have a question here about subnetting, it says "a host is configured with automatic IP-settings. What adress-space indicates the inability to communicate with a DHCP server? And I have these options, I know it's option C, but why is it option C?

Here are the options :

A: 169.254.0.X with netmask 255.255.255.0

B: 169.254.X.X with netmask 255.255.0.0

C: 169.254.X.X with netmask 255.255.255.0

D: 169.255.X.X with netmask 255.255.0.0
