Explanation: 

Detailed explanation-1: -Which of the protocols listed below was designed as a secure replacement for Telnet? Secure MIME (S/MIME) is an enhanced version of the MIME protocol that enables email security features by providing encryption, authentication, message integrity, and other related services.

Detailed explanation-2: -SSH was designed as a replacement for Telnet and for unsecured remote shell protocols such as the Berkeley rsh and the related rlogin and rexec protocols. Those protocols send information, notably passwords, in plaintext, rendering them susceptible to interception and disclosure using packet analysis.

Detailed explanation-3: -The key difference between Telnet and SSH is that SSH uses encryption, which means that all data transmitted over a network is secure from eavesdropping. SSH uses the public key encryption for such purposes. Like Telnet, a user accessing a remote device must have an SSH client installed.
