You are loading CSV files from Cloud Storage to BigQuery. The files have known data quality issues, including mismatched data types, such as STRINGs and
INT64s in the same column, and inconsistent formatting of values such as phone numbers or addresses. You need to create the data pipeline to maintain data quality and perform the required cleansing and transformation. What should you do?

A. Use Data Fusion to transform the data before loading it into BigQuery. B. Use Data Fusion to convert the CSV files to a self-describing data format, such as AVRO, before loading the data to BigQuery. C. Load the CSV files into a staging table with the desired schema, perform the transformations with SQL, and then write the results to the final destination table. D. Create a table with the desired schema, load the CSV files into the table, and perform the transformations in place using SQL.
