Wont the proxy server always do a redirection, even if the destination IP is the original webserver? A debug should reveal a 301 move, especially if the request is the server IP address. I think the key is the browser configuration which is redirected to proxy. I think answer is B, though the question was meant to confuse readers.

Selected Answer: C
For the transparent proxy method, the request contains the destination IP address of the web server and the proxy transparently intercepts the client request (either by being in-line or by traffic steering). There is no client configuration and Panorama is optional. Transparent proxy requires a loopback interface, User-ID configuration in the proxy zone, and specific Destination NAT (DNAT) rules. Transparent proxy does not support X-Authenticated Users (XAU) or Web Cache Communications Protocol (WCCP). https://docs.paloaltonetworks.com/pan-os/11-0/pan-os-new-features/networking-features/web-proxy
