Q50 Single choice

The code block displayed below contains an error. The code block is intended to write DataFrame transactionsDf to disk as a parquet file in location /FileStore/transactions_split, using column storeId as key for partitioning. Find the error.

Code block:

transactionsDf.write.format("parquet").partitionOn("storeId").save("/FileStore/transactions_s plit")A.

A
The format("parquet") expression is inappropriate to use here, "parquet" should be passed as first argument to the save() operator and "/FileStore/transactions_split" as the second argument.
B
Partitioning data by storeId is possible with the partitionBy expression, so partitionOn should be replaced by partitionBy.
C
Partitioning data by storeId is possible with the bucketBy expression, so partitionOn should be replaced by bucketBy.
D
partitionOn("storeId") should be called before the write operation.
E
The format("parquet") expression should be removed and instead, the information should be added to the write expression like so: write("parquet").
