Explanation:
The correct answer is D: Create a custom Compute Engine image from a snapshot. Create your instances from that image. Creating a custom image from a snapshot ensures that you have a reusable and consistent boot disk for your new instances. Snapshots alone are not directly usable for creating instances; they need to be converted to images first. This approach is more efficient and reliable when you need to create multiple instances with the same configuration.
