Why each option
TCP is the only connection-oriented protocol among the listed options, establishing a reliable communication session before transmitting data.
IP (Internet Protocol) is a connectionless protocol, primarily responsible for addressing and routing packets without guaranteeing delivery or order.
UDP (User Datagram Protocol) is a connectionless protocol that offers a faster but unreliable service without establishing a connection or guaranteeing delivery.
DNS (Domain Name System) primarily uses UDP for most queries but can use TCP for zone transfers; however, it is not inherently a connection-oriented data transfer protocol itself for typical queries.
The Transmission Control Protocol (TCP) is a connection-oriented protocol that establishes a reliable, ordered, and error-checked connection between two endpoints before transmitting data. It ensures data delivery through mechanisms like sequence numbers, acknowledgments, and retransmissions.
This is incorrect as IP and UDP are distinctly connectionless protocols.
