Answer - B - APIPA service is used to assign an IP address to your computer when it does not find an IP address from a DHCP server.

Key Takeaway: APIPA is used when a computer is not assigned an IP address by the DHCP server.. When a Windows-based computer configured for DHCP is initializing, it broadcasts 3 or more Discover messages. If a DHCP server does not respond after several discover messages are broadcast, the Windows computer assigns itself a Class B or APIPA address. Then the Windows computer will display an error message to the user. The Windows computer will then send out a Discover message every three minutes in an attempt to establish communications with a DHCP server.
