You use Terraform to manage an application deployed to a Google Cloud environment. The application runs on instances deployed by a managed instance group. The Terraform code is deployed by using a CI/CD pipeline. When you change the machine type on the instance template used by the managed instance group, the pipeline fails at the terraform apply stage with the following error message:

You need to update the instance template and minimize disruption to the application and the number of pipeline runs.
What should you do?

A. Delete the managed instance group, and recreate it after updating the instance template. B. Add a new instance template, update the managed instance group to use the new instance template, and delete the old instance template. C. Remove the managed instance group from the Terraform state file, update the instance template, and reimport the managed instance group. D. Set the create_before_destroy meta-argument to true in the lifecycle block on the instance template.
