Why each option

FTPS (FTP Secure) wraps FTP communications in TLS/SSL encryption, making it the most secure dedicated file transfer protocol among the options listed.

AFTP

FTP transmits all data including credentials in plaintext, providing no confidentiality or integrity protection.

BFTPSCorrect

FTPS adds TLS (or SSL) encryption to the traditional FTP protocol, protecting both the control channel (credentials) and the data channel (file contents) from interception. Among the choices, it is the only protocol specifically designed for secure file transfer with full channel encryption.

CSSH

SSH provides a secure encrypted shell session and can facilitate file transfer via SCP or SFTP as sub-protocols, but SSH itself is a remote access protocol, not a dedicated file transfer protocol.

DTELNET

TELNET transmits all data in plaintext and has no encryption, making it one of the least secure protocols for any purpose.
