Answer: A

Explanation:

According to VMware’s documentation, the "No Data Migration" option for maintenance mode should be used when the expected maintenance time is less than one hour. This option will allow the administrator to complete their maintenance without having to wait for a full data migration, which can be time consuming and also has additional capacity and performance considerations. It is important to note that this option will not guarantee the same level of availability as the other options, so it should only be used when the expected maintenance time is less than one hour.
