B. storesDF.write.mode("overwrite").text(filePath) Explanation: write.mode("overwrite") sets the mode for writing the DataFrame, with overwrite indicating that any existing data at the target location should be overwritten. .text(filePath) writes the DataFrame to the specified file path in text file format.
