A team is refactoring a monolithic Terraform configuration into modules. They have a module that creates an Azure virtual network and outputs the subnet IDs. Another module creates a network security group and needs the subnet IDs to associate rules. The team wants to pass the subnet IDs from the first module to the second module. What is the correct approach?

In the root configuration, reference the first module's output and pass it as an input variable to the second module.

In the second module, directly reference the first module's output using module.vnet.subnet_ids.

Copy the subnet IDs manually into the second module's variables.

Use a data source in the second module to fetch the subnet IDs from Azure.
