This is the variable type that you could use for this input, as it can store multiple attributes of different types within a single value. The other options are either invalid or incorrect for this use case.

 This is the command that you would use to access all of the attributes and details of a resource managed by Terraform, by providing the resource address as an argument. For example, terraform state show 'aws_instance.example' will show you all the information about the AWS instance named example.

Theversion argumentin a module ensures Terraform uses aspecific versionof a module, preventing unintended updates.

A (source)– Specifies the module source butdoes not control versioning.

B (count)– Controls how many instances of a resource/module exist,not updates.

D (lifecycle)– Controls how resources behavebut does not control module versioning.

Official Terraform Documentation Reference:

Module Version Constraints

A module cannot always refer to all variables declared in its parent module, as it needs to explicitly declare input variables and assign values to them from the parent module’s arguments. A module cannot access the parent module’s variables directly, unless they are passed as input arguments.
