Explanation

'Data Link Layer' is a term from the OSI model, not the TCP/IP architecture - in the TCP/IP model, the equivalent combined layer is called the 'Network Access' or 'Link' layer. The Application, Transport, and Internet layers are all legitimate TCP/IP model layers, making Data Link Layer the correct answer as the one that does NOT belong.
