Selected Answer: BE
These file formats are optimized for analytics and support features like columnar storage, which is beneficial for query acceleration, making them more efficient for querying in big data analytics workloads. Parquet: A columnar storage format that is widely used for analytics, providing fast query performance. Avro: A row-based storage format that also supports efficient querying, particularly with its schema support and compact data format. So, Parquet and Avro are the correct answers.
