My pick: it's B. In Dynamics, the document table is what you use to define and introduce the main entity like non-conformities. The others are more for details or history. I've seen similar logic in the official docs and some practice tests. Someone correct me if supplemental ever works for the core entity?
Option B makes more sense to me. The document table sets up the core entity definition, not just the history. A is a trap since document history is about tracking changes, not introducing the entity. If I’m misunderstanding the role of the supplemental table though, let me know.
