Which of the following describes how Amazon EC2 Auto Scaling groups can be used to scale capacity in the AWS Cloud?

Amazon EC2 Auto Scaling groups automatically adjust the number of EC2 instances in a group based on defined policies and demand. This ensures applications have sufficient capacity during peak loads and reduces costs during low demand by terminating unnecessary instances. "Use serverless EC2 instances" is incorrect because EC2 instances are not serverless; they are virtual servers. Serverless compute is provided by services like AWS Lambda. "Automatically change the instance types (size) of EC2 instances based on demand" is incorrect; while Auto Scaling can launch different instance types, its primary function is scaling out (adding instances) or in (removing instances), not dynamically changing the type of existing instances. "Move unused CPU capacity from one EC2 instance to another" is incorrect; EC2 instances are independent virtual machines, and their CPU capacity cannot be directly transferred between them.
