Explanation

Telnet provides remote command-line access to a device but transmits all data, including credentials, in cleartext. SSH (Secure Shell) is its direct, encrypted replacement - it provides the same remote shell functionality over an encrypted channel using strong cryptography (typically operating on port 22 vs. Telnet's port 23). SFTP (B) is SSH File Transfer Protocol, used for secure file transfers, not interactive shell sessions. SSL (C) is a transport-layer encryption protocol used as the foundation for HTTPS, not a remote shell protocol. HTTPS (D) is HTTP over SSL/TLS for secure web browsing, not a Telnet replacement. SSH is the accepted industry standard substitute for Telnet.
