The correct option is B Protocol

Protocol the term used for set of rules that governs data communication.

A communications protocol defines the rules for sending blocks of data (each known as a Protocol Data Unit (PDU)) from one node in a network to another node. Protocols are normally defined in a layered manner and provide all or part of the services specified by a layer of the OSI reference model.

Popular protocols include: File Transfer Protocol (FTP), TCP/IP, User Datagram Protocol (UDP), Hypertext Transfer Protocol (HTTP), Post Office Protocol (POP3), Internet Message Access Protocol (IMAP), Simple Mail Transfer Protocol (SMTP).

Protocols are often described in an industry or international standard. The TCP/IP Internet protocols, a common example, consist of: Transmission Control Protocol (TCP), which uses a set of rules to exchange messages with other Internet points at the information packet level.
