How can the user configure this?

An organization has configured two single availability zones. The Auto Scaling groups are configured in
separate zones. The user wants to merge the groups such that one group spans across multiple zones. How
can the user configure this?

A.
Run the command as-join-auto-scaling-group to join the two groups

B.
Run the command as-update-auto-scaling-group to configure one group to span across zones and
delete the other group

C.
Run the command as-copy-auto-scaling-group to join the two groups

D.
Run the command as-merge-auto-scaling-group to merge the groups

Explanation:
If the user has configured two separate single availability zone Auto Scaling groups and wants to merge them
then he should update one of the groups and delete the other one. While updating the first group it is
recommended that the user should increase the size of the minimum, maximum and desired capacity as a
summation of both the groups.
