Which approach should a Service Cloud Consultant use to ensure that Lightning Knowledge searches only...

Data Categories in Salesforce Knowledge are used to organize and control access to articles based on defined topics—such as product specializations. By assigning data category visibility via permission sets or profiles, agents only see articles relevant to their assigned categories.

Option A (record types) affects article layout and authoring, not search visibility.

Option C (private sharing) is overly restrictive and not intended for Knowledge filtering by product.
