Explanation
ICMP is designed specifically to communicate network health and diagnostic information between devices. It is used by tools like ping (tests reachability) and traceroute (maps packet paths), and delivers error messages such as 'Destination Unreachable' or 'Time Exceeded.' ARP (B) resolves IP-to-MAC addresses, RARP (A) resolves MAC-to-IP addresses, and IP (C) is the core addressing and routing protocol - none of which are primarily focused on network health messaging.
