Which of the following statement is incorrect, provided there is an auto-scaling group setup using launch configuration, with a default termination policy for scale in?

Answer options:

A.Determine unprotected instances in the selected Availability Zone which uses the oldest launch configuration. If there is one such instance, terminate it.
B.Determine unprotected instances in the selected Availability Zone use the newest launch configuration. If there is one such instance, terminate it.
C.If multiple instances use the oldest launch configuration, determine which unprotected instances are closest to the next billing hour and terminate it.
D.If there is more than one unprotected instance closest to the next billing hour, select one of the instances randomly.

Answer: B
Option B is the only false statement, the rest of them are true statements.
The default termination policy applies multiple termination criteria before selecting an instance to terminate. When Amazon EC2 Auto Scaling terminates instances, it first determines which Availability Zones have the most instances, and it finds at least one instance that is not protected from scale-in.
Determine whether any of the instances eligible for termination use the oldest launch template or configuration:
[For Auto Scaling groups that use a launch template]
Determine whether any of the instances use the oldest launch template unless there are instances that use a launch configuration. Amazon EC2 Auto Scaling terminates instances that use a launch configuration before it terminates instances that use a launch template.
[For Auto Scaling groups that use a launch configuration]
Determine whether any of the instances use the oldest launch configuration.
After applying the preceding criteria, if there are multiple unprotected instances to terminate, determine which instances are closest to the next billing hour. If there are multiple unprotected instances closest to the next billing hour, terminate one of these instances at random.
