Answer: Migrate the workload to a Compute Engine VM. Start and stop the instance as needed.
The correct answer is C: 'Migrate the workload to a Compute Engine VM. Start and stop the instance as needed.' Preemptible VMs and nodes (options A, B, and D) are not suitable because preemptible instances can only run for up to 24 hours and can be stopped at any time, which means they cannot complete a task that takes 30 hours and must be restarted if interrupted. On the other hand, a standard Compute Engine VM (option C) can run for the necessary 30 hours uninterrupted and can be started and stopped as needed, ensuring the batch process completes successfully.
