Ah, the age-old question: which MongoDB aggregate command is the fastest? I'm going to go with C and hope I don't end up in an infinite loop of aggregation.

Wait, is this a trick question? If the aggregate command is the one with the pipeline, then why would the other options even be there? I hope the exam isn't full of these types of curveballs!

All of the above? I'm pretty sure the aggregate command is the one that uses a pipeline. Group and mapReduce have their own unique approaches.
