D Correct answer
Explanation

VPN technology uses encryption and tunneling protocols to provide confidentiality, which prevents unauthorized parties from reading the contents of data communications. Even if traffic is intercepted, the encrypted data is unreadable without the decryption keys. QoS manages traffic priority, latency refers to delay, and reliability ensures delivery - none of these prevent data from being read if intercepted.
