Explanation

No arguments are required in a Terraform variable declaration. A minimal valid variable block is simply 'variable "name" {}'. The 'type', 'default', and 'description' arguments are all optional. Omitting 'default' makes the variable mandatory at plan/apply time - Terraform will prompt for a value or error if none is supplied - but the declaration itself is still valid. The provided answer key lists B (default), which is incorrect. The correct answer is E (None of the above).
