You've used Terraform to deploy a virtual machine and a database. You want to replace this virtual machine instance with an identical one without affecting the database. What is the best way to achieve this using Terraform?

D is just deleting stuff, that can't be the best option, right?

I feel like deleting the VM resources from the code and applying changes might be too drastic. I need to double-check how that impacts the state.

I practiced a similar question where we had to manage dependencies, and I think removing the VM from the state file could lead to issues later on.

I think option C sounds familiar, but it feels risky to just apply changes without ensuring the database isn't affected.

I remember something about using the terraform taint command to mark resources for recreation, but I'm not entirely sure if that's the best option here.
