Which fully managed AWS service assists with the creation, testing, and management of custom Amazon EC2 images?

Explanations:

EC2 Image Builder is a fully managed AWS service for automating the creation, testing, and management of EC2 images.

Amazon Machine Image (AMI) is an image format, not a managed service for building, testing, or managing images.

AWS Launch Wizard helps deploy enterprise applications, not manage EC2 image creation or testing.

AWS Elastic Beanstalk is for deploying applications, not for managing custom EC2 image creation or testing.
