B & E results an output. But using df.schema gives you the schema in more detail, df.printSchema just gives the columns that are present in the dataframe. df.printSchema() gives the detailed schema.

interesting case, either the answer E is indeed not complete () is missing or it is B, though B doesn't print schema but returns schema object
