   A healthcare organization runs a multi-tenant Hadoop cluster where each business unit must see only its own data. The compliance team needs a full audit trail of who accessed which datasets and when, and data scientists need to trace the lineage of a derived dataset back to its source. The security team wants to enforce column-level restrictions on sensitive patient records. Which combination of tools should the organization implement?

   • AApache Atlas for lineage and classification, Apache Ranger for fine-grained access control and audit logging, Apache Knox as the perimeter gateway for authentication and SSO
   • BApache Ranger for lineage and classification, Apache Atlas for fine-grained access control, Apache Knox for REST API access control
   • CApache Atlas for fine-grained access control, Apache Ranger for lineage tracking, Apache Knox for audit logging
   • DApache Knox for lineage and classification, Apache Atlas for perimeter security, Apache Ranger for single sign-on
