Answer: D

Explanation:

The SSL proxy can detect if encryption is being used by looking at the destination port number of the packet. If the port number is 443, then the proxy can assume that the packet is being sent over an encrypted connection. If the port number is different, then the proxy can assume that the packet is not encrypted. For more information, please refer to the Juniper Networks JNCIS-SEC Study Guide.
