Answer: B

Explanation:

"You can use terraform state rm in the less common situation where you wish to remove a binding to an existing remote object without first destroying it, which will effectively make Terraform "forget" the object while it continues to exist in the remote system." https://www.terraform.io/cli/commands/state/rm
