Is it just me, or does option C seem off?

Definitely not B, wrong nombre!

Wait, why is there an "aficion" field in A? That's weird.

I think it's actually option D, it fits the query perfectly.

Option A looks correct, matches both nombre and apellido.

I’m leaning towards option D, but I’m a bit confused about the ObjectId format in the answers.

I feel like option A is close, but I can't recall if the 'apellido' should match exactly.

I remember practicing a similar question, and I think the fields in the projection part matter a lot.

I think the query is looking for a specific document, but I'm not sure if it returns the correct fields.

I've got a good strategy for this. I'll start by extending the SalesLineType class and then add the new method that returns the day of the week. Hopefully, that will do the trick!

Okay, so we need to automatically delete the fields when importing the updated solution. I'm pretty sure "Upgrade" is the correct choice, but I'll review the options just to be sure.

I guess it could be A since it's about low risk, but I've seen other questions where that didn't apply. Need to think this one through!
