C? Really? Embedding collections should be the exception, not the rule. What are they thinking?

But what if the many is very large? Wouldn't it be better to use a separate collection then?

Definitely B. If the many is very large, embedding it just sounds like a recipe for a bloated document. Separate collections are the way to go.

I agree with Eladia. It would be more efficient to embed the collection in that case.

I think when the many is not very large, an embedded collection makes the most sense. It keeps the data nicely organized and easy to access.
