"A communication between two devices is over the maximum limit of an ethernet frame size. The Transmission Control Protocol (TCP) splits up the data into segments. Which field in the header helps keep track of the many segments?"

The Field in the header that will helps keep track of the many segments is the : Sequence number

Hello the options related to your question is missing but the correct answer have been provided above

The sequence number in a Transmission control protocol ( TCP ) helps keep count of the number of byte been sent out by a host.  The sequence number is also a TCP segment, because the sequence number increases in proportion to the number of bytes contained in the TCP packet.

Hence we can conclude that the Field in the header that helps keep track of the many segments is the sequence number

Explanation:

TCP/IP, or the Transmission Control Protocol/Internet Protocol, is a suite of communication protocols used to interconnect network devices on the internet. TCP/IP can also be used as a communications protocol in a private network (an intranet or an extranet).The sequence number in a header is used to keep track of which segment out of many this particular segment might be. The next field, the acknowledgment number, is a lot like the sequence number. The acknowledgment number is the number of the next expected segment.The 32 bit sequence number field defines the number assigned to the first byte of data contained in this segment. TCP is a stream transport protocol. To ensure connectivity, each byte to be transmitted is numbered.
