Explanation
State Manager ensures that all instances launched by the Auto Scaling group automatically receive the desired configuration which immediately applies when instances are launched. While the primary focus of Option D is on patch management (applying updates and patches) rather than configuring the overall state of the operating system. Using Run Command is very AD-hoc which means you need to time the launching of the EC2 instance with the command and might not provide the continuous assurance that the configuration is maintained.
