Answer - B.
The Elastic Beanstalk service is the ideal service to quickly provision development environments.
You can also create environments that can be used to host Docker-based containers.
Option A is incorrect since using Opswork is best suited when you have multiple stacks and want to use configuration tools for the environment.
Options C and D are incorrect since this would involve a lot of effort in deployment.

The correct answer for this question would be B. Create an application and Environment for the Docker containers in the Elastic Beanstalk service.
Explanation: Elastic Beanstalk is a fully-managed service provided by AWS that allows developers to deploy applications quickly and easily. Elastic Beanstalk supports a wide variety of programming languages and platforms, including Docker containers. Elastic Beanstalk abstracts the underlying infrastructure, allowing developers to focus on writing code and deploying their applications.
When migrating an existing development environment consisting mainly of Docker-based containers, using Elastic Beanstalk would ensure that minimum effort is taken during the migration process. The Elastic Beanstalk service abstracts the underlying infrastructure, allowing developers to focus on deploying their Docker containers, without worrying about the underlying infrastructure.
Creating an application and environment for the Docker containers in Elastic Beanstalk is a straightforward process. Developers can simply upload their Docker containers to Elastic Beanstalk, and Elastic Beanstalk will handle the deployment and scaling of the containers. Elastic Beanstalk also provides a web-based console and a command-line interface (CLI) for managing the environment, including scaling and monitoring.
Option A, creating an Opswork stack and deploying the Docker containers, is not the best option in this scenario. While OpsWorks is another fully-managed service provided by AWS, it is better suited for more complex applications and infrastructures. Using OpsWorks to deploy Docker containers would require more effort than using Elastic Beanstalk.
Option C and D, creating an EC2 instance, installing Docker, and deploying the necessary containers, is a viable option. However, this approach would require more effort and would not be as scalable or automated as using Elastic Beanstalk. Additionally, using EC2 instances would require more management and maintenance than using Elastic Beanstalk. Option D, adding an Autoscaling Group, would provide scalability for the containers, but would also require more management and configuration than using Elastic Beanstalk.
