Your company is loading comma-separated values (CSV) files into Google BigQuery. The data is fully imported successfully; however, the imported data is not matching byte-to-byte to the source file. What is the most likely cause of this problem?

A. The CSV data loaded in BigQuery is not flagged as CSV. B. The CSV data has invalid rows that were skipped on import. C. The CSV data loaded in BigQuery is not using BigQuery's default encoding. D. The CSV data has not gone through an ETL phase before loading into BigQuery.
