Consider the three-way hand shaking process followed during TCP connection establishment between two hosts A and B. Let S and R be two random 32-bit starting sequence numbers chosen by A and B, respectively. Suppose A sends a TCP segment having SYN bit =1, SEQ number = S and ACK bit = 0 and B accepts the connection request.
Which one of the following choices represents the information present in the TCP segment header that is sent by B to A?
