The 3-way handshake method is used by the TCP protocol to establish a connection between a client and the server. It involves three steps:
1. In the first step, a SYN message is sent from a client to the server.
2. In the second step, a SYN/ACK message is sent from the server to the client.
3. In the third step, an ACK (usually called SYN-ACK-ACK) message is sent from the client to the server. At this point, both the client and the server have received acknowledgements of the TCP connection.
If the Initial Sequence Numbers of the client and server were 241713111 and 241824111 respectively at the time when the client was sending the SYN message in the first step of the TCP
3-way handshake method, what will be the value of the acknowledgement number field of the server's packet when the server was sending the SYN/ACK message to the client in the second step of the TCP 3-way handshake method?

• A.241713112
• B.241824111
• C.241713111
• D.241824112
