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 programs involved in the transfer: a client program on the user’s computer and a server program on the remote computer. The client program initiates the connection and requests a file transfer, and the server program responds by sending the file to the client.
FTP is a very simple protocol, but it is very reliable and efficient. It is the most common way to transfer files over the Internet, and it is supported by all major operating systems.
