Yes, A seems correct according to MuleSoft's own documentation. But since Dataweave version 2.5, the documentation also says that the lookup function is deprecated and that flow reference is recommended instead.

That's true, I'm guessing we won't get any Lookup questions but instead we will get flow-ref.
