Answer 1

The fields used in a TCP segment header are: Source port, Acknowledgment number, and Window size.

Step-by-step explanation:

The fields used in a TCP segment header are: Source port, Destination port, Sequence number, Acknowledgment number, TCP header length, Reserved bits, Control flags, Window size, Checksum, and Urgent pointer.

Out of the given options, the fields used in a TCP segment header are: Source port, Acknowledgment number, and Window size (option C).

The source port is the port number used by the source device to send the TCP segment, the acknowledgment number is used to acknowledge received data segments, and the window size specifies the number of bytes the sender is willing to receive.
