   • AContinuous delivery with a manual approval gate before production deployment
   • BContinuous integration only, with no automated deployment to staging
   • CContinuous deployment with fully automated production releases
   • DManual deployment to production after each code change

   A startup is building a file-processing application that runs only when a new file is uploaded to cloud storage. The team expects low and sporadic usage, and wants to minimize operational overhead. They also need to ensure that the processing code is automatically tested before deployment. Which combination of architecture and practice best meets these requirements?

   • ADeploy a serverless function triggered by the storage upload event, and use a CI/CD pipeline that runs unit tests before deployment.
   • BDeploy a containerized application on a Kubernetes cluster, and use a CI/CD pipeline that runs only build steps.
   • CRun a virtual machine that polls the storage bucket every minute, and use a CI/CD pipeline that runs integration tests after deployment.
   • DUse a serverless function but skip the CI/CD pipeline to speed up deployment.
