Consider the following command to add a new disk group called "tdgroupA" with two failover groups： CREATE DISKGROUP tdgroupA NORMAL REDUNDANCY FAILOVERGROUP control01 DISK ’/devices/A1’，  ’/devices/A2’，  ’/devices/A3’  FAILOVERGROUP control02 DISK ’/devices/B1’，  ’/devices/B2’，  ’/devices/B3’m  The disk "/devices/A1" is currently a member disk of a disk group by the name "tdgroup1".  Which task would be accomplished by the command？（）

A.This command would result in an error because a disk group can have only one failover group.

B.This command would result in an error because the /devices/A1 disk is a member of another disk group tdgroup1.

C.A new disk group called tdgroupA will be added with two failover groups and the /devices/A1 disk will get reattached to the new disk group without being detached from the existing one.

D.A new disk group called tdgroupA will be added with two failover groups and the /devices/A1 disk will be ignored for the new disk group because it is a member of an existing disk group tdgroup1.

E.A new disk group called tdgroupA will be added with two failover groups and the /devices/A1 disk gets detached from the existing disk group tdgroup1 and attached to the new disk group tdgroupA
