    I think B is correct.. I can use IAM and delete / reset Access key pair and if EC2 was running with that specific key, and not used by any other EC2, that means i used IAM to stop access to specific EC2

    It’s not clear what “allow or deny access to a specific instance” means in this question.

    There is nothing about OS level access, so it can be API or Console access to perform action on specified instance. This You can limit using IAM Policy.
