What is the correct sequence for the TCP three-way handshake?

Drag & Drop
A flow-controlled connection is established.
The initiating host sends a packet with no data to the target host with a SEQ=1 and sets the SYN flag to 1.
The initiating host sends a packet with SEQ=2, ACK=9, and ACK flag is raised.
The target host sends a packet with ACK=2, SEQ=8, and the SYN and ACK flags are set to 1.
Explanation

TCP connection establishment uses the three-way handshake: the initiating host sends SYN, the target replies with SYN and ACK, and the initiator sends the final ACK. The connection is established after that final acknowledgement.
