5B is the one you want. When a DoS wipes your disk data, your fastest path back to a working server is getting your data restored from backup, which is exactly what the backup service is there for, and none of the other options get you operational data without one.
I almost went with C because when I hear "all disk data is lost" my instinct from years of ops work is to call a recovery specialist, but then I remembered that disk recovery is expensive, slow, and not guaranteed, while your backup service already has a clean copy of your data sitting there ready to restore. If you have a backup service and you are not calling them first, you are making the recovery ten times harder than it needs to be.
Samuel makes the right call and it is worth adding that the question stem says "immediately," which is the qualifier that eliminates disk recovery right away since that process is anything but immediate.
All disk data lost, so C, recover data first before anything.
The data being gone does not change what you boot from. B is correct because you boot from the installation media first to access recovery tools, then the repair process handles what is recoverable from there.
