Why each option
UDP is a lightweight, connectionless transport protocol known for its simplicity, featuring minimal error checking and lacking built-in recovery mechanisms.
UDP includes an optional checksum primarily for detecting corrupted datagrams, but it does not provide retransmission or error correction, signifying its limited error checking capabilities.
UDP is a connectionless protocol and does not utilize defined timers for connection management, retransmissions, or flow control, unlike connection-oriented protocols like TCP.
UDP offers no inherent mechanisms for recovering lost packets, flow control, or congestion control, meaning it does not attempt to retransmit data if it fails to reach its destination.
The three-way handshake is a connection establishment procedure specific to TCP, which UDP, being a connectionless protocol, does not employ.
