Explanation

UDP (User Datagram Protocol) is connectionless - it sends data packets (datagrams) directly to the destination without first establishing a dedicated connection, performing a handshake, or guaranteeing delivery or order. This makes it fast and suitable for real-time applications like video streaming, VoIP, and DNS queries. TCP (B) is connection-oriented and uses a three-way handshake (SYN, SYN-ACK, ACK) before data transfer. SSH (A) and HTTPS (C) are application-layer protocols that run on top of TCP, inheriting its connection-oriented nature.
