I thought it would return the last 10 comments, not just 5.

It returns 5 comments starting from the last 10.

I’m confused about whether it starts counting from the last 10 comments or if it just returns the last 5 comments.

I remember practicing a similar question where negative values indicated starting from the end of the array, so maybe it’s option A?

I think the $slice operator is supposed to return a subset of an array, but I'm not entirely sure how the negative index works in this context.

I feel like I saw something about how $slice can take two parameters, but I can't recall exactly how they interact.

Okay, I'm feeling pretty confident about this one. I think Option C is the way to go - creating a Triggered Send and then enabling the custom Reply Mail Management settings to send the auto-reply. That should do the trick.
