What should an administrator consider when planning to revert Panorama to a pre-PAN-OS 8.1 version?
An administrator cannot revert Panorama to an earlier PAN-OS release if variables are used in templates or template stacks. This restriction exists because variables, introduced in later versions, are not compatible with earlier releases, preventing a straightforward downgrade.
A is correct You are unable to downgrade from PAN-OS 8.1 to an earlier PAN-OS release if variables are used in your template or template stack configuration. Variables must be removed from the template and template stack configuration to downgrade.

A is correct
