    A database is stored in an Automatic Storage Management (ASM) disk group, disk group, DGROUP1 with SQL:There is enough free space in the disk group for mirroring to be done.What happens if the CONTROLLER1 failure group becomes unavailable due to error of for maintenance?（）

    A. Transactions and queries accessing database objects contained in any tablespace stored in DGROUP1 will fall.

    B. Mirroring of allocation units will be done to ASM disks in the CONTROLLER2 failure group until the CONTROLLER1 for failure group is brought back online.

    C. The data in the CONTROLLER1 failure group is copied to the controller2 failure group and rebalancing is initiated.

    D. ASM does not mirror any data until the controller failure group is brought back online, and newly allocated primary allocation units (AU) are stored in the controller2 failure group, without mirroring.

    E. Transactions accessing database objects contained in any tablespace stored in DGROUP1 will fail but queries will succeed.
