I practiced a question like this before, and I believe a data flow diagram shows processes, not definitions. So, data dictionary feels right.

Data lineage seems more about tracking data movement rather than defining metrics, right?

I'm not entirely sure, but I remember something about data explainability reports being more about transparency in models, not metrics.

A - Data dictionary. The only thing missing is a glossary of buzzwords to go with it.

D - Data flow diagram. Because if it's not in a pretty diagram, it doesn't exist. Might as well just hand in a blank piece of paper and call it a day.
