Analysis of Incorrect Options:
A: Importing is not needed since one VM is already in state.
B: terraform apply doesn’t show which VM ID is managed, it only refreshes attributes.
C: Removing state entries is destructive and may lead to losing state data unnecessarily.
Key Concept:The state file is Terraform’s source of truth for which resources it manages.
