The correct answer is A, EC2 Image Builder. This fully managed AWS service is designed to simplify the process of creating, testing, and deploying custom Amazon EC2 images. It reduces the effort of keeping images up-to-date and secure by providing a simple graphical interface, built-in automation, and AWS-provided security settings. With EC2 Image Builder, there are no manual steps for updating an image, nor is it necessary to build your own automation pipeline. The other options, while related to AWS services, do not specifically focus on the creation and management of custom EC2 images. Amazon Machine Image (AMI) is a type of image, not a service for creating them. AWS Launch Wizard helps with launching applications, and AWS Elastic Beanstalk is for deploying and scaling web applications, not specifically for managing EC2 images.
