Choose a match for every item. Use each answer once.

TCP handles retransmission and ordering while exposing a stream rather than preserving application message boundaries.

ARP discovers the local hardware address needed for link-level delivery of IPv4 packets.

UDP leaves reliability and ordering decisions to the application or higher-level protocol.

ICMP helps communicate network conditions rather than carrying ordinary application data streams.
