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!

Hmm, the pipeline approach for aggregation? Sounds like they're trying to make our lives easier by optimizing the performance. C gets my vote!

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.
