The correct answer is D. 4. Terraform evaluates variable values in a strict precedence order, from lowest to highest: (1) default value in the variable block (3), (2) TF_VAR_ environment variables (TF_VAR_itemNum=9), (3) terraform.tfvars / .auto.tfvars files (7), (4) -var or -var-file flags on the command…

Use the Terraform CLI (terraform plan, apply, destroy, fmt, init, validate, workspace, import, taint, providers, output)

Explanation

Terraform evaluates variable values in a strict precedence order, from lowest to highest: (1) default value in the variable block (3), (2) TF_VAR_* environment variables (TF_VAR_itemNum=9), (3) terraform.tfvars / *.auto.tfvars files (7), (4) -var or -var-file flags on the command line (4). The -var flag has the highest precedence and always wins. Note that TF_itemNum is NOT a valid Terraform environment variable - only variables prefixed with TF_VAR_ are recognized. Because the command includes -var itemNum=4, the final value is 4.
