terraform refresh command will not modify infrastructure, but does modify the state file.
Correct Answer:
A
The terraform refresh command is used to reconcile the state Terraform knows about (via its state file) with the real-world infrastructure. This can be used to detect any drift from the last-known state, and to update the state file. This does not modify infrastructure, but does modify the state file.
