B.
Seal MP1.
C.

D.

Explanation:
When you create a group, you save it to an unsealed management pack.
However, an element in an unsealed management pack, such as a group, cannot reference an
element in a different unsealed management pack, such as an override or a view.
If you are going to use a group to target an override or scope a view, you must either save the group
to the same unsealed management pack as the override or view, or you must seal the management
pack that contains the group.
If you save the group to the same unsealed management pack as the override or view, you can only
use that group for overrides and views that are also contained in that unsealed management pack.
If you seal the management pack that contains the group, you can reference that group from other
unsealed management packs.However, you cannot easily change any group settings in the sealed management pack or add new
groups to the sealed management pack.
