   A DevOps engineer is reviewing a Terraform configuration that manages an Azure virtual machine. The configuration includes a resource block for the VM. The engineer wants to understand what happens when they run `terraform apply` after changing only the VM's `tags` argument. What will Terraform do?

   • ATerraform will fail because tags cannot be changed after the VM is created.
   • BTerraform will only update the state file with the new tags and not touch the actual VM.
   • CTerraform will update the VM in place by applying the new tags, leaving other attributes unchanged.
   • DTerraform will destroy the VM and create a new one with the new tags.
