Answer: Delta Lake provides built-in support for versioning and data lineage, which can be accessed using the `DESCRIBE HISTORY` and `DESCRIBE DATALINEAGE` statements.
Option C is the correct answer because Delta Lake indeed offers native support for versioning and data lineage through specific SQL statements. This feature is crucial for compliance, auditing, and understanding data evolution over time without the need for external tools or custom logic. Options A, B, and D either incorrectly state that Delta Lake does not support these features or suggest unnecessary workarounds.

C
Delta Lake provides built-in support for versioning and data lineage, which can be accessed using the DESCRIBE HISTORY and DESCRIBE DATALINEAGE statements.
D
Versioning and data lineage can be implemented using custom application logic or third-party libraries, but are not directly supported by Delta Lake.
