Answer: Use the Swap Environment URLs feature in AWS Elastic Beanstalk.
The correct answer is B. AWS Elastic Beanstalk provides a Swap Environment URLs feature specifically for blue/green deployments. This feature allows you to switch the CNAME records of two environments, thereby directing traffic from the old environment (blue) to the new environment (green) seamlessly. This method is built into Elastic Beanstalk and is the recommended approach for performing such updates.
