Explanation

The correct method to print a DataFrame's schema is storesDF.printSchema(). This prints the schema as a formatted tree showing each column's name, data type, and nullability (e.g., |-- division: string (nullable = true)). The property storesDF.schema also exists but returns a StructType object rather than printing anything. Option E fills in blank 2 with printSchema(), which is the only method in the Spark DataFrame API that produces printed schema output.
