Answer: storesDF.write.mode(“overwrite”).parquet(filePath)
The correct code block must use the DataFrameWriter's methods correctly. Option C uses `write.mode("overwrite").parquet(filePath)`, which is the proper syntax for writing a DataFrame as Parquet, overwriting existing files. Other options have issues: A uses incorrect syntax for `write`, B incorrectly calls `write()`, D misuses `option` and `path`, and E uses `path` instead of `parquet` or `save`.
