Which solution will meet these requirements?

A DevOps engineer is tasked with moving a mission-critical business application running in Go to AWS. The development team running this application is understaffed and requires a solution that allows the team to focus on application development. They also want to enable blue/green deployments and perform A/B testing.

Which solution will meet these requirements?
A . Deploy the application on an Amazon EC2 instance and create an AMI of this instance. Use this AMI to create an automatic scaling launch configuration that is used in an Auto Scaling group. Use an Elastic Load Balancer to distribute traffic. When changes are made to the application, a new AMI is created and replaces the launch configuration.
B. Use Amazon Lightsail to deploy the application. Store the application in a zipped format in an Amazon S3 bucket Use this zipped version to deploy new versions of the application to Lightsail. Use Lightsail deployment options to manage the deployment.
C. Use AWS CodePipeline with AWS CodeDeploy to deploy the application to a fleet of Amazon EC2 instances. Use an Elastic Load Balancer to distribute the traffic to the EC2 instances. When making changes to the application, upload a new version to CodePipeline and let it deploy the new version.
D. Use AWS Elastic Beanstalk to host the application. Store a zipped version of the application in Amazon S3, and use that location to deploy new versions of the application using Elastic Beanstalk to manage the deployment options.
