Which set of layers makes up the TCP/IP stack?

Explanation:
The TCP/IP model is built in four layers: Application, Transport, Internet (Network), and Network Access (Data Link). The set that lists Application, Transport, Network, Data Link matches those four layers, mapping to top-level protocols (like HTTP, SMTP), transport reliability and multiplexing (TCP/UDP), IP addressing and routing (Internet), and the local-network transmission (Data Link). The other options mix in OSI-specific layers (Session, Presentation, Physical) or omit a layer, so they don’t fit the TCP/IP structure.
