Explanation

FTP (File Transfer Protocol) uses port 21 by default for the control connection. This is the well-known port assigned by IANA for FTP, and it's one of the fundamental network port numbers that administrators should memorize. The other options (12, 23, 32) are associated with different services or are not standard FTP ports.
