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

The command used to show a resource in the Terraform state is indeed "terraform state show." This command directly interacts with the state file where Terraform stores the current state of your infrastructure. By using this command, you can view detailed information about a specific resource, including its metadata and attributes as they are currently defined in the state.

The other options provided do not perform this specific function. "terraform display" is not a recognized command in the Terraform CLI. "terraform show" is used to display the contents of the Terraform state or a plan file, but it does not target a specific resource in the state file like "terraform state show" does. Lastly, "terraform resource show" does not exist in the Terraform command set, further emphasizing that it cannot be used to retrieve resource details from the state.

Understanding the purpose and functionality of these commands is crucial for effectively managing and querying your infrastructure through Terraform.
