Selected Answer: A
 Immutable system is a virtual machine or container that cannot be modified once it's created. Any changes require the creation of a new, identical VM with the desired modifications. This ensures that the original VM remains unchanged and secure, with data stored externally. Since the system is immutable, there's no risk of unauthorized alterations to the existing VM. If a change is needed, a new immutable VM is spun up with the updated configuration.

Selected Answer: A
The immutable system approach aligns with the requirements by ensuring VMs are protected against unauthorized changes and requiring new deployments for updates or modifications. This approach enhances security, maintains integrity, and supports efficient management of VM instances in cloud environments.
