   An NGINX reverse proxy forwards requests to a backend that requires the X-Forwarded-Host header to be set to the original Host header, but only when the request comes from a trusted IP range. For other clients, the header should be removed. Which configuration achieves this?

   • Aproxy_set_header X-Forwarded-Host $host;
   • Badd_header X-Forwarded-Host $host;
   • Cif ($remote_addr ~ 10\.0\.) { proxy_set_header X-Forwarded-Host $host; }
   • Dmap $remote_addr $forwarded_host { 10.0.0.0/8 $host; default ''; } proxy_set_header X-Forwarded-Host $forwarded_host;
