Answer is D. The cache space is limited, so you will only see recent certificates cached if you have a busy firewall. But the certificates in that certificate cache are placed there when the firewall retrieves the certificate for a traffic flow that matches an SSL Forward Proxy decryption policy. Note that the end-entity certificate is the final link in the chain of trust.
