Answer: 16 MB

The correct answer is C (16 MB) based on Snowflake documentation and community consensus. According to Snowflake's official documentation for the COPY INTO <location> command, the default MAX_FILE_SIZE parameter is 16777216 bytes, which equals 16 MB. This is confirmed by multiple community members who reference the official documentation, with one comment providing the specific documentation link and another explaining that this default allows for parallel operations during data unloading. All other options (5 MB, 8 GB, 32 MB) are incorrect as they do not match Snowflake's documented default value for file size when unloading data.
