Answer: JSON, Parquet, CSV

The question asks for three supported file formats for unloading data from Snowflake. Based on Snowflake documentation and the community discussion consensus (with BCF having 100% agreement and multiple upvoted comments confirming it), the correct answers are JSON (B), Parquet (C), and CSV (F). JSON and Parquet are optimal for structured/semi-structured data unloading with efficient compression, while CSV is widely supported for delimited data. XML (A) is not supported for unloading (only loading), as clarified in the discussion. ORC (D) and AVRO (E) are not supported for unloading in Snowflake, despite being used for semi-structured data loading in some contexts.
