Explanation

In the TCP/IP model, IP (Internet Protocol) operates at the Internet (network) layer — it handles addressing and routing of packets, not application services. FTP (File Transfer Protocol), HTTP (HyperText Transfer Protocol) and DNS (Domain Name System) all operate at the application layer, providing services directly to end-user applications. Hence IP is the odd one out — option D.
