Answer: Move to committed-use instances
**Correct Answer:** Committed use instances offer the lowest cost for long-term projects, with commitments of 1 or 3 years. Since the project will run for 12 months, it qualifies for the discount provided by committed use instances. **Why Other Options Are Incorrect:** - **Preemptible instances**, while cost-effective for batch processing, are unsuitable here due to their interruptible nature, which contradicts the requirement for uninterrupted processing. - **Standard instances** are the most expensive option and do not optimize costs. - **Switching to Cloud Functions** involves re-platforming overhead and does not necessarily guarantee cost optimization for this specific use case. For more information, refer to [preemptible instances](https://cloud.google.com/compute/docs/instances/preemptible) and [committed use discounts](https://cloud.google.com/compute/docs/instances/signing-up-committed-use-discounts).

A
Switch from the standard compute instances to Cloud Functions.
B
Use the current set of instances because they are the cheapest.
C
Move to preemptible instances
D
Move to committed-use instances
