In a TCP header, which field is 16 bits long and represents the source port?

Explanation:
In TCP, the header carries two 16-bit fields that identify the endpoints of the connection: the Source Port and the Destination Port. The field that represents the port number of the sending application is the Source Port, and it is 16 bits long so it can hold values from 0 to 65,535. The Destination Port is also 16 bits, identifying the port on the receiving end. The other two fields mentioned, Sequence Number and Acknowledgment Number, are 32 bits each and serve for data ordering and reliability, not for identifying endpoints.
