Show answer & explanation
Correct answer: C
Key idea: TLS encrypts communication between email clients and mail servers, or between mail servers, when configured for secure transport.
SMTP is used to send email, and POP/IMAP are used to retrieve email.
TLS provides the encryption layer used to protect those email connections.
SSH is for secure remote login and tunneling, not the standard email-encryption protocol in this context.
Answer: Option 2, “TLS”, is correct.
