Answer: Apply for committed-use discounts.
The correct answer is **B** because committed-use discounts offer the greatest savings for predictable, long-term workloads, aligning perfectly with the scenario's requirements. - **Why Other Options are Less Suitable**: - **A (Utilize Standard VMs)**: This option incurs the highest cost without any discounts. - **C (Use preemptible VMs)**: While cost-effective, preemptible VMs do not guarantee high availability as they can be terminated by Google. - **D (Sustained-use discounts for the VMs)**: Although this provides discounts, they are not as substantial as those from committed-use discounts for predictable, long-term usage. Refer to Google Cloud's documentation on [Resource-based committed use discounts](https://cloud.google.com/compute/docs/instances/signing-up-committed-use-discounts) and [Sustained use discounts](https://cloud.google.com/compute/docs/sustained-use-discounts) for more details.
