REV and RIN don’t sound familiar at all. I’m pretty certain it’s not those, but I can’t recall the exact details.

I’m leaning towards PTR as well, but I feel like I might be mixing it up with another record type.

I'm confident the answer is PTR. That's the record type used to map IP addresses to hostnames in reverse DNS lookups.

Okay, let me think this through. Reverse DNS is when you look up a hostname based on an IP address, so the record type has to be something that supports that functionality. I'll go with PTR.

The key here is that the question is asking about reverse DNS queries, so the answer has to be related to that. I think PTR is the right choice.
