In my opinion none of the answers are correct: when upgrading, the firewall will reboot and the cluster will run only on one member for a while, so no session synchronisation until it reboots.

Option C When you upgrade from one PAN-OS feature release version to a later feature release, you cannot skip the installation of any feature release versions in the path to your target release. In addition, the recommended upgrade path includes installing the latest maintenance release in each release version before you install the base image for the next feature release version. https://docs.paloaltonetworks.com/pan-os/10-1/pan-os-upgrade/upgrade-pan-os/upgrade-the-firewall-pan-os/determine-the-upgrade-path.html
