DP-600 Exam Question - Parameterization

I am taking the practice exam right now for DP-600 and I am trying to figure out why this question is incorrect.

When I look at the single link provided for help, it describes that Dataflows Gen2 does have this capability here:

Can someone explain why this is wrong, or did the AI that created this test get it wrong?

I find it extremely difficult to take these practice exams, especially while trying to answer AI-created questions from AI-created documentation.
