As DBA for the Rebel Alliance you have decided that you need to facilitate some redundancy in your database. Using ASM， you want to create a disk group that will provide for the greatest amount of redundancy for your ASM data （you do not have advanced SAN mirroring technology available to you， unfortunately）. 
Which of the following commands would create a disk group that would offer the maximum in data redundancy？（）
