Which command is used to show a resource in the Terraform state?

The command used to show a resource in the Terraform state is "terraform state show." This command allows users to inspect the details of a specific resource as it is represented in the Terraform state file. The state file contains essential information about the infrastructure managed by Terraform, including the current configuration and metadata of the resources.

When you use "terraform state show" followed by the resource address, it provides detailed information such as the attributes and any changes to the resource since it was last applied. This is particularly useful for debugging and verifying the current state of resources without having to consult the cloud provider's interface.

Understanding this command is crucial as it provides visibility into the actual state of your infrastructure as Terraform tracks it, thereby helping you align your configurations with what is deployed. The other choices do not correspond to valid Terraform commands associated with showing resources in the state file.
