Answer: Option B

Explanation:

TCP/IP protocols map to a four - layer conceptual model known as the DARPA modal, named after the U.S government agency that initially developed TCP/IP. The four layers of the DARPA model are: Application, Transport, Internet and Network Interface. Each layer in the DARPA model corresponds to one or more layers of the seven - layer Open Systems Interconnection (OSI) model.
