   A company uses Terraform to manage its infrastructure. They have a CI/CD pipeline that runs 'terraform plan' on every pull request. The pipeline also runs 'terraform apply' automatically when a pull request is merged to the main branch. However, a recent change to the Terraform configuration caused a production outage because the change was applied without proper review. What should the team do to prevent this?

   • ARequire a manual approval step before 'terraform apply' runs in the pipeline.
   • BUse a different tool that does not require a plan step.
   • CRun 'terraform apply' only on a schedule, not on every merge.
   • DRemove the 'terraform plan' step from the pipeline to speed up deployments.
