To efficiently manage access to public report and dashboard folders for a group of users (like sales managers), using a Public Group is the best practice. Public Groups can be used to define access centrally and avoid manual updates.
* Option A: Sharing via the Role Hierarchy provides hierarchical access but does not allow specific access control for folders.
* Option B: Sharing folders with a profile is not supported in Salesforce.
* Option C (Correct): Sharing folders with a Public Group ensures efficient and automated access management for sales managers.
