Answer: A

Explanation:

The prefix -/+ means that Terraform will destroy and recreate the resource, rather than updating it in-place.

The prefix ~ means that some attributes and resources can be updated in-place. $ terraform apply

aws_instance.example: Refreshing state… [id=i-0bbf06244e44211d1] An execution plan has been generated and is shown below. Resource actions are indicated with the following symbols: -/+ destroy and then create replacement

Terraform will perform the following actions:
