This looks like a straightforward question about the first step in a Rolling Update. I'd say the best answer is D - Back up your applications, database schema, other application data, and domains. That's always the safest first step before making any major changes.
Okay, let's see. I remember learning about drive wiping, degaussing, and purging as ways to securely erase data. I think physical destruction is the most thorough, but I'll double-check the details on the other options just to be sure.
