Explanation:
To read a Parquet file into a DataFrame, the correct sequence starts with the SparkSession (spark), followed by .read, and then specifying the Parquet file using .parquet(filePath). Option C (4, 3, 6) correctly chains these steps as spark.read.parquet(filePath). Other options are invalid due to incorrect method calls (e.g., .read() instead of .read) or incorrect parameters (e.g., source="parquet" instead of format="parquet").
