You Need to Create a Traditional Third-Mirror Breakoff Snapshot in Disk

You need to create a traditional third-mirror breakoff snapshot in disk group "testdg" on a volume named "testvol". You've used the vxassist command to start the creation of the snapshot, synchronizing in the background. How do you determine whether the snapshot is ready?

A) Use "vxprint -g testdg -ht testvol" to display the status of testvol, and check the STATE column of the vxprint output; if the snapshot plex is ready, its state will be "ACTIVE".
B) Use "vxprint -g testdg -ht testvol" to display the status of testvol, and check the STATE column of the vxprint output; if the snapshot plex is ready, its state will be "SNAPATT".
C) Use "vxprint -g testdg -ht testvol" to display the status of testvol, and check the STATE column of the vxprint output; if the snapshot plex is ready, its state will be "SNAPDONE".
D) Use "vxprint -g testdg testvol" to display the status of testvol, and check the STATE column of the vxprint output; if the snapshot plex is ready, its state will be "SNAPATT".
