Answer: A,B

Explanation:

TCP Finite State Machine (FSM) States, Events and Transitions + CLOSED: This is the default state that each connection starts in before the process of establishing it begins.

The state is called "fictional" in the standard.

+ LISTEN

+ SYN-SENT

+ SYN-RECEIVED: The device has both received a SYN (connection request) from its partner and sent its own SYN. It is now waiting for an ACK to its SYN to finish connection setup.

+ ESTABLISHED

+ CLOSE-WAIT

+ LAST-ACK

+ FIN-WAIT-1

+ FIN-WAIT-2

+ CLOSING

+ TIME-WAIT
