Suggested answer: D

Explanation:

In the Transmission Control Protocol (TCP) header, the sequence number field is crucial for ensuring the correct sequencing of the packets sent over a network.

The sequence number field in the TCP header is 32 bits long, which equates to 4 bytes.

This sequence number is used to keep track of the bytes in a sequence that are transferred over a TCP connection, ensuring that packets are arranged in the correct order and data integrity is maintained during transmission.
