A Defect Was Discovered in Production and a New Sprint

Multiple Choice

A defect was discovered in production and a new sprint item has been created for deploying a hotfix. However, any code change must go through the following steps before going into production: Scan the code for security breaches, such as password and access key leaks. Run the code through extensive, long-running unit tests. Which source control strategy should a DevOps Engineer use in combination with AWS CodePipeline to complete this process?

A) Create a hotfix tag on the last commit of the master branch. Trigger the development pipeline from the hotfix tag. Use AWS CodeDeploy with Amazon ECS to do a content scan and run unit tests. Add a manual approval stage that merges the hotfix tag into the master branch.
B) Create a hotfix branch from the master branch. Trigger the development pipeline from the hotfix branch. Use AWS CodeBuild to do a content scan and run unit tests. Add a manual approval stage that merges the hotfix branch into the master branch.
C) Create a hotfix branch from the master branch. Trigger the development pipeline from the hotfix branch. Use AWS Lambda to do a content scan and run unit tests. Add a manual approval stage that merges the hotfix branch into the master branch.
D) Create a hotfix branch from the master branch. Create a separate source stage for the hotfix branch in the production pipeline. Trigger the pipeline from the hotfix branch. Use AWS Lambda to do a content scan and use AWS CodeBuild to run unit tests. Add a manual approval stage that merges the hotfix branch into the master branch.
