Answer: 4, 3, 6
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"`).
