Correct Answer: D.
The wizard performs a policy search to find all policies in preparation for import into the FortiManager database. You may choose to import all firewall policies, or select specific policies to import. If you choose to import only specific policies into the policy package and later install policy changes, the policies that were not imported will be deleted locally on FortiGate. This is because FortiManager does not have those policies in the policy package. - FortiManager 7.4 Administrator Study Guide - Page No:190
