Which of these is stored in the .

Detailed Explanation:

Rationale for Correct Answer: Terraform uses the .terraform directory as working-directory data and caches downloaded dependencies there, including modules and provider/plugin-related files. HashiCorp ' s tutorial describes .terraform as containing modules and plugins used to provision infrastructure.

Analysis of Incorrect Options (Distractors):

A: .terraform.lock.hcl is stored in the root working directory, not inside .terraform.

C: With the default local backend, terraform.tfstate is normally in the working directory, not the .terraform dependency directory.

D: .tf configuration files belong in the module ' s working directory.

Key Concept: Terraform working-directory structure and initialization artifacts.
