C. Multiple interfaces can be selected as incoming and outgoing interfaces.
This statement is correct. You can specify multiple interfaces as both incoming and outgoing interfaces in a firewall policy.
D. A zone can be chosen as the outgoing interface.
This statement is correct as well. In FortiGate firewalls, you can choose a zone as the outgoing interface in a firewall policy, providing a convenient way to apply policies to multiple physical or logical interfaces grouped under the same zone.
So, the correct choices are C and D.

If Override DISABLED then: ports > HA Uptime > Priority > SN.
If Overrrid ENABLED then: ports > Priority > HA Uptime > SN.
The FortiGate election process when the HA override setting is disabled follows the criteria you provided:
Connected monitored ports: The FortiGate with more connected monitored ports is preferred.
HA uptime: The FortiGate with the longer High Availability (HA) uptime (less recently rebooted in HA) is preferred.
Priority: Priority is used as a tiebreaker. If two FortiGates have the same number of connected monitored ports and the same HA uptime, the one with the higher priority is preferred.
FortiGate Serial number: The FortiGate Serial number is used as a final tiebreaker if all other criteria are the same.
