spark.read().schema(“schema”).csv(filePath)

spark.read.schema(schema).csv(filePath)

spark.read.schema(“schema”).csv(filePath)

spark.read().schema(schema).csv(filePath)

Correct Answer: C

To read a CSV file into a DataFrame with a specified schema using Spark, you would use the spark.read.schema method and provide the schema as an argument. The correct syntax for doing this is spark.read.schema(schema).csv(filePath), where schema is the variable containing the schema definition and filePath is the path to the CSV file.
