• EBronze tables contain raw data with a schema applied.

• A
  7% (4)
• B
  2% (1)
• D
  4% (2)
• E

Explanation

In the Medallion Architecture, Bronze tables represent the first landing zone for raw ingested data. The key distinction between Bronze tables and raw data files is that Bronze tables apply a schema to the data - adding metadata such as ingestion timestamps, source file paths, and data types - while preserving the original content as-is without filtering or transformation. Raw files (CSV, JSON, Parquet, etc.) have no enforced schema in the lakehouse context. Bronze does not reduce data volume (A), does not add truthfulness (B), does not aggregate (C), and is more refined than raw (not less, ruling out D). Answer E correctly identifies that Bronze = raw data + schema applied.
