The answer 21 is correct because FTP (File Transfer Protocol) uses port 21 as the default port for establishing a connection between a client and a server. This port is specifically designated for FTP data transfer and is used to initiate the control connection between the client and server. Through this control connection, commands and responses are exchanged to facilitate file transfers. Therefore, port 21 is crucial for FTP communication and is the correct answer in this context.
