A team stores raw files in its own S3 bucket and registers them as an external Unity Catalog table. Which statement correctly distinguishes this from a managed table?

1. The table cannot participate in lineage because its files are external
2. All storage access is revoked automatically when the external table is dropped
3. The team retains responsibility for the external data lifecycle; Unity Catalog still governs table access
4. Registering the table copies its files into managed storage
