One instance in your VPC is configured to run with a private IP address only. You want to ensure that even if this instance is deleted, its current private IP address will not be automatically assigned to a different instance.
In the GCP Console, what should you do?

A. Assign a public IP address to the instance. B. Assign a new reserved internal IP address to the instance. C. Change the instance's current internal IP address to static. D. Add custom metadata to the instance with key internal-address and value reserved.
