Which of these commands makes your code more human readable?

• A. terraform plan
• B. terraform validate
• C. terraform output
• D. terraform fmt

Answer: (D)

Readable Terraform code comes from consistent formatting. terraform fmt rewrites your configuration files to a canonical style, standardizing indentation, spacing around equals, and line breaks. This makes the code easier to read and review across a team. Other commands have different purposes: plan shows what changes would occur without changing the code, validate checks syntax and basic correctness without altering formatting, and output displays computed values after applying. Because terraform fmt directly affects the human readability of the code by enforcing a standard format, it is the best choice for making your code more readable.
