To read a JSON file with a specified schema in PySpark, the correct sequence involves starting with the SparkSession, followed by the DataFrameReader, and then the json method with the file path and schema. The correct order is .spark \, .read \, and .json(filePath, schema = schema), which corresponds to lines 3, 5, and 1. This sequence is represented by option C. Other options either use incorrect methods or parameters, such as .read() which is not a valid method call, or .json(filePath, format = schema) which incorrectly uses format instead of schema.
