It's definitely the Meet-in-the-middle attack!

I feel like I’ve seen something about the Meet-in-the-middle attack being less secure than using a single key, but I can't recall the details clearly.

I’m a bit confused; I thought the Man-in-the-middle attack was more about intercepting communications, not specifically about DES.

I remember practicing a question about attacks on DES, and I think the Meet-in-the-middle was mentioned there too.

I think the answer might be the Meet-in-the-middle attack, but I'm not entirely sure. It sounds familiar from my notes.

I'm leaning towards Option A because Fred seems to have a nosocomial complication, which is a hospital-acquired issue.

I'm uncertain... could it be that all listed IPs are just restricted for access, or is it about blocking them entirely?
