Answer: C

Explanation:

When you migrate your project, it will no longer inherit the policies from its current place in the resource hierarchy, and will be subject to the effective policy evaluation at its destination. We recommend making sure that the effective policies at the project’s destination match as much as possible the policies that the project had in its source location. https://cloud.google.com/resource-manager/docs/project-migration#import_export_folders

Policy inheritance can cause unintended effects when you are migrating a project, both in the source and destination organization resources. You can mitigate this risk by creating specific folders to hold only projects for export and import, and ensuring that the same policies are inherited by the folders in both organization resources. You can also set permissions on these folders that will be inherited to the projects moved within them, helping to accelerate the project migration process.
