As someone who's been on a MongoDB binge lately, I can confirm that A), B), and C) are all MIA in that database. Gotta keep it simple, stupid!

B) Joins? More like 'B) Byes' in MongoDB! Amirite?

I also believe multi-statement transactions were omitted for scalability reasons.

I'm going with B) and C) here. Authentication is a must-have, but joins just slow things down when you're dealing with big data.

I'd say A) and B) were both deliberately left out. MongoDB is all about that NoSQL life, ya know?

Yes, that's correct. Joins can be expensive in terms of performance.

Definitely B) Joins. MongoDB sacrifices joins for horizontal scalability, so that's a key feature that was omitted.
