A Correct answer
Explanation

ARP (Address Resolution Protocol) is the correct protocol used to find the hardware (MAC) address of a device on a local network when you know its IP address. RARP (Reverse ARP) does the opposite - it finds an IP address from a known MAC address. ICMP is used for diagnostic messages (like ping), and PING is a tool that uses ICMP, not a protocol itself. PONG is not a real networking protocol.
