C.

Explanation:
The correct answer is “Takes an IP address and finds out the MAC address to which it belongs”. ARP
starts with an IP address, then queries the network to find the MAC or hardware address of the
workstation to which it belongs. ICMP performs “Sends messages to the devices regarding the health
of the network”. RARP performs “Takes a MAC address and finds an IP address to match”. FTP
performs “Facilitates file transfers”.
