Final answer:
The payload section of TCP segments includes source and destination port numbers, sequence and acknowledgement numbers, and the data being transmitted. So, the correct answer is 2) Source and destination port numbers.
Step-by-step explanation:
The payload section of TCP segments includes source and destination port numbers, sequence and acknowledgement numbers, and the data being transmitted.
The source port number is used to identify the sender's port, while the destination port number identifies the receiver's port. These port numbers allow the sender and receiver to establish a connection and ensure that the data reaches the correct destination.
The sequence number indicates the order in which the TCP segments should be reassembled at the receiver's end. The acknowledgement number is used to confirm the successful receipt of the data segments.
The data being transmitted refers to the actual information being sent from the sender to the receiver over the network. It could be a file, a webpage, an email, or any other form of digital content.
Thus, the correct answer is 2) Source and destination port numbers.
