Answer: gcloud compute instances create preempt --preemptible --no-boot-disk-auto-delete
The correct answer is **A** because creating a preemptible instance requires the `--preemptible` flag, and to ensure the disk contents are not deleted upon instance termination, the `--no-boot-disk-auto-delete` flag must be included. This setup allows the disk contents to be reused if the VM is preempted. - **Option B** is incorrect due to the wrong parameter for disk retention. - **Option C** is incorrect as it lacks the necessary flag to prevent disk deletion upon termination. - **Option D** is incorrect because it does not specify the instance as preemptible.
