Answer is:
WIRL
Explanation:
WIRL is not a protocol used in the Internet. Telnet, HTTP, and Gopher are all application-layer protocols that are commonly used in the Internet.
Telnet is a protocol that allows users to connect to and interact with remote computers over a network.
HTTP is the protocol used for the World Wide Web, and it enables the transfer of hypertext documents.
Gopher is another protocol for distributing, searching, and retrieving documents over the Internet, although it is less widely used today.
