D . 2

Answer: C

Explanation:

Auto Scaling is an AWS service that allows you to increase or decrease the number of EC2 instances within your application’s architecture. With Auto Scaling, you create collections of EC2 instances, called Auto Scaling groups. You can create these groups from scratch, or from existing EC2 instances that are already in production.
