I don't think the receiving router sends a notification for missing attributes; that seems more like a characteristic of well-known mandatory attributes.

I feel like option B sounds familiar, but I can't recall if they are really discarded if not recognized.

I think well-known discretionary attributes are supposed to be recognized by all peers, but I'm not sure if they need to be included in every update.

I remember practicing a question about BGP attributes, and I think the key point was that they can be optionally included in updates.

I'm a bit confused by the options. I'll need to re-read the question and the choices to make sure I understand.
