B.
Reverse address resolution protocol (RARP).
C.

RARP is used to find the IP address when the hardware (MAC) address is known.

C: CSMA/CD is the physical medium access method used by hardware protocols such a Ethernet.
It is not directly involved with addressing.
D: A DNS server performs IP to NAME mappings. Neither is a hardware address.
