C) doesn't make much sense to me. I've never heard of the SSH host key being a 'root key' for signing user keys. Sounds like something out of a Dan Brown novel.

D) is an interesting one, but I don't think that's quite right. The host key is about verifying the server, not the user. Maybe the exam writers were trying to throw us off with that one.
