Which statement is true about Telnet security?

Explanation:
Telnet transmits all data in plaintext, including usernames and passwords, so there is no encryption or confidentiality for the session. That’s why the statement that Telnet provides no encryption is true. Telnet doesn’t use certificates for authentication, and it doesn’t require SSH to work—it’s a separate protocol entirely. In practice, because there’s no built‑in encryption, Telnet is insecure for remote access and is largely replaced by SSH in modern networks.
