Wait, are we supposed to index views now? I thought that was just for tables. This exam is getting way too complicated.

C seems plausible, but the output doesn't mention anything about the temptable processing algorithm. I'd go with B to play it safe.

But the statement mentions about the index on the Name column, so I still think A is the right choice.

Ha! Looks like someone forgot to set the is_updatable attribute on the view. D is definitely not the right answer.

I think the correct answer is B. myview cannot be automatically indexed. The output clearly shows that the underlying table's index on the Name column is being used, so A is incorrect.
