Answer

(i) Error reporting

Explanation

IP is responsible for logical addressing, packet/datagram format, and packet handling/routing conventions. However, IP itself is a connectionless best-effort delivery protocol and does not provide error reporting as a core IP function.

Error reporting for IP-related delivery problems is provided by ICMP (Internet Control Message Protocol), which works alongside IP.

Therefore, among the given choices, error reporting is not directly an IP function.

Final answer: (i) Error reporting.
