Dear Experts,
Can anyone please let me know how option "C" is the answer to Question 31 for PracticeExam-DataEngineerAssociate.
Since option "C" contains the average function it can't be the correct option as aggregation is from the Silver to the Gold table as per my understanding.

I agree that I would not put it as the correct option as it can be controversial as we make calculations and not only data cleaning.
But anyway I would choose C
as A and B contains aggregation, and agg means gold.
D and E are copying data without changes, so it is still bronze.

Question 17 is even worse.
"A data engineer is overwriting data" vs "should simply be overwritten instead"
One situation I assume is DROP and CREATE and another is INSERT INTO OVERWRITE but here both are called the same.
A data engineer is overwriting data in a table by deleting the table and recreating the table.
Another data engineer suggests that this is inefficient and the table should simply be
overwritten instead.
