Question #: 2
Topic #: 1

The code block displayed below contains an error. The code block should return all rows of DataFrame transactionsDf, but including only columns storeId and predError. Find the error.

Code block:

spark.collect(transactionsDf.select("storeId", "predError"))
A.

Instead of select, DataFrame transactionsDf needs to be filtered using the filter operator.

B.

Columns storeId and predError need to be represented as a Python list, so they need to be wrapped in brackets ([]).

C.

The take method should be used instead of the collect method.

D.

Instead of collect, collectAsRows needs to be called.

E.

The collect method is not a method of the SparkSession object.
