In a Private sharing model, users cannot see records they do not own unless they are shared. An Owner-based Sharing Rule is the standard way to grant this access at scale. By creating a rule that shares records owned by members of a " Sales Reps " Public Group with that same Public Group, the administrator allows all reps to see each other ' s accounts. Furthermore, because Account and Opportunity share a relationship, the sharing rule can be configured to grant " Read Only " (or higher) access to the associated Opportunity records simultaneously. Option B is incorrect because simply placing a report in a folder does not bypass record-level security (users will see an empty report). Option C and D are inefficient for granting broad, group-based access that can be handled via standard configuration.
