The statement contains a factual error. The TCP three-way handshake (SYN, SYN-ACK, ACK) is used exclusively to establish a connection. To terminate or disable a connection, TCP uses a separate four-way handshake process (FIN, ACK, FIN, ACK). While it is true that TCP supports reliable data transmission, the premise that the three-way handshake is used for both establishing and disabling connections is incorrect, making the entire statement false. TCP's reliability is primarily achieved through mechanisms like sequence numbers, acknowledgments, and data retransmission, not the handshake process alone.

A. Claiming the statement is true ignores the four-way termination defined in RFC 793, so it is wrong.

- J. Postel, "RFC 793 - Transmission Control Protocol," Section 3.5 "Closing a Connection," September 1981. This foundational document specifies the four-packet exchange (four-way handshake) for closing TCP connections.
