Why each option

Data lineage's primary purpose in data engineering is to trace and document the origin, transformations, and movement of data throughout its lifecycle.

ATo optimize query performance.

Optimizing query performance is related to data storage, indexing, and query tuning, not the primary purpose of data lineage itself.

BTo transform data formats.

Transforming data formats is a function of ETL processes, which data lineage helps document but is not its core purpose.

CTo trace the source and flow of data.Correct

Data lineage provides a clear audit trail that tracks where data came from, how it was transformed, and where it moved over time. This traceability is crucial for debugging, ensuring data quality, meeting compliance requirements, and understanding the impact of changes.

DTo create visualizations.

Creating visualizations is a function of business intelligence and reporting tools, which consume data that data lineage helps understand.
