Which of the following transport layer protocols is connection-oriented and guarantees reliable packet delivery?
Show answer & explanation
Answer: B. TCP
Transmission Control Protocol (TCP) establishes a connection via a 3-way handshake and ensures reliable, in-order delivery via sequence numbers and acknowledgements.

Step 2: It provides guaranteed delivery via retransmissions and error checking.
