How can you do this safely?

You’re building a CI/CD (continuous integration/continuous delivery) pipeline and need to inject sensitive variables into your Terraform run.

How can you do this safely?
A . Copy the sensitive variables into your Terraform code
B . Store the sensitive variables in a secure_varS.tf file
C . Store the sensitive variables as plain text in a source code repository
D . Pass variables to Terraform with a -var flag

Answer: D

Explanation:

This is a secure way to inject sensitive variables into your Terraform run, as they will not be stored in any file or source code repository. You can also use environment variables or variable files with encryption to pass sensitive variables to Terraform.
