You have defined the values for your variables in the file terraform.tfvars, and saved it in the same directory as your Terraform configuration. Which of the following commands will use those values w

While `terraform plan` alone does work due to automatic loading, it is not the only correct option as explicitly using `-var-file` also works.

While `terraform plan -var-file=terraform.tfvars` works, it is not the only correct option as `terraform plan` alone also works due to automatic loading.

Terraform automatically discovers and loads variable definitions from files named `terraform.tfvars` or `*.auto.tfvars` present in the current working directory. Additionally, the `-var-file` parameter allows explicit specification of a variable definition file, overriding or merging with other variable sources. Since `terraform.tfvars` is automatically loaded, both `terraform plan` and `terraform plan -var-file=terraform.tfvars` will successfully use the defined values.

Both option A and option B are valid methods for Terraform to load variables from `terraform.tfvars`, making this choice incorrect.
