Which capability of PAN-OS would address the customer's lack of visibility?

A. single pass architecture (SPA), because it will improve the performance of the Palo Alto Networks Layer 7 inspection capability
B. App-ID, because it will give visibility into what exact applications are being run over that port and allow the customer to block unsanctioned applications using port 53
C. User-ID, because it will allow the customer to see which users are sending traffic to external destinations over port 53
