Best Answer Explained in Below-:

The correct answer to the question "Which of the following is used to transfer files?" is C) FTP, which stands for File Transfer Protocol. FTP is specifically designed for transferring files over a network. It allows users to upload, download, and manage files on a remote server. The protocol operates on the client-server model, where a user, through an FTP client, can connect to an FTP server to initiate file transfers.

In contrast, option A) HTTP (Hypertext Transfer Protocol) is primarily used for transferring hypertext documents and web pages on the internet, not specifically for file transfer, even though it can facilitate downloading files in a web context. Option B) HTML (Hypertext Markup Language) is a markup language used to create and structure content on web pages, not a method for file transfer. Option D) None of these is incorrect as FTP explicitly serves the file transfer purpose. Thus, FTP stands out as the best choice for transferring files, highlighting its dedicated functionality within network protocols.
