D is definitely wrong. You can't change the ASM compatible attributes for an existing disk group. I'd go with B and E.

Yes, B and E are the correct choices. The disk group can contain ADVM volumes and files have two copies for each allocation unit.

I think B and E are the correct answers. The disk group can contain ADVM volumes, and the files have one primary and one secondary copy by default.
