Answer: A

Explanation:

When you update a stack with an Auto Scaling group and scheduled action, AWS CloudFormation always sets the min size, max size, and desired capacity properties of your Auto Scaling group to the values that are defined in the AWS::AutoScaling::AutoScalingGroup resource of your template, even if a scheduled action is in effect.

Auto Scaling based on a schedule allows the user to scale the application in response to predictable load changes. The user can also configure the recurring schedule action which will follow the Linux cron format. If the user is setting a recurring event, it is required that the user specifies the Recurrence value (in a cron format., end time (not compulsory but recurrence will stop after this. and the Auto Scaling group for which the scaling activity is to be scheduled.
