The selection of SSH as the correct answer is based on its fundamental role in providing secure communication over unsecured networks. SSH, or Secure Shell, is indeed a secured version of Telnet that encrypts the data transmitted between a client and server, thus protecting sensitive information from being intercepted by malicious actors.

SSH operates primarily over TCP Port 22 and facilitates secure remote login, command execution, and file transfers, distinguishing it from the unencrypted transmission commonly associated with Telnet. This is particularly important in environments where sensitive data is transmitted, as SSH's encryption ensures that eavesdroppers cannot read the information being exchanged.

Other options like SSL and TLS are cryptographic protocols that provide an additional layer of security, typically used for securing communications over the internet, such as HTTPS. However, they do not directly replace Telnet. PPTP (Point-to-Point Tunneling Protocol) is used for implementing virtual private networks (VPNs) and is not specifically related to Telnet-like sessions. Therefore, SSH is the most appropriate choice for this question regarding secure communication over Telnet's original purpose.
