From where can EC2 instances be launched?

Any S3 bucket
Amazon Machine Images (AMI)
Elastic Load Balancers (ELB)
CloudFormation templates

The correct answer is: Amazon Machine Images (AMI)

The correct answer is based on the fact that Amazon Machine Images (AMIs) serve as the foundational template used to launch EC2 instances. An AMI contains the necessary information required to create a fully functional EC2 instance, including the operating system, application server, and applications. When you launch an EC2 instance, you select an AMI that defines the environment and resources available to the instance. This flexibility allows for the easy replication of environments across instances, making AMIs essential to the EC2 instance creation process. Other options serve different purposes within the AWS ecosystem. For instance, S3 buckets are primarily used for object storage and do not directly contribute to launching EC2 instances. Elastic Load Balancers are used to distribute incoming traffic across multiple EC2 instances but are not involved in the instance launch process itself. CloudFormation templates enable you to model and provision AWS resources in a consistent manner, but they define infrastructure as code rather than directly provide the OS and settings needed for launching an individual instance.
