A packet that is already associated with a current session arrives at the firewall.
What is the flow of the packet after the firewall determines that it is matched with an existing session?

When a packet that is already associated with a current session arrives at the firewall, it is sent through the fast path because session establishment is not required. If subject to content inspection, it will pass through a single stream-based content inspection engine before egress. This ensures efficient processing and reduces latency by avoiding repeated inspection steps.
D is correct

it's D - "stream-based content inspection" https://www.paloaltonetworks.com/resources/whitepapers/single-pass-parallel-processing-architecture
D is correct
That's the idea of single pass software inspection
