Selected Answer: B
Parquet (choice B) is a columnar storage format that: Minimizes storage size via efficient compression and encoding. Supports efficient read/ingestion (particularly for column-based queries). Stores schema information (including data types) within its metadata. JSON and XML can be verbose, and while CSV is relatively small, it does not store data types or other schema information inherently. Hence, Parquet is the best fit.
