The correct answer is A. File Transfer Protocol.

FTP is a standard network protocol used to transfer files from one computer to another over a TCP/IP network, such as the Internet. FTP is a client-server protocol, which means that there are two types of computers involved in the transfer: a client and a server. The client initiates the transfer by connecting to the server and requesting a file. The server then sends the file to the client.

FTP is a very versatile protocol and can be used to transfer any type of file, including text files, images, programs, and even entire operating systems. It is a very common protocol and is supported by most operating systems and web browsers.
