D.

Suggested answer: B

Explanation:

On-Demand Instances are most cost-effective for short-term, steady, and unpredictable workloads. Using them for a one-month testing period allows flexibility without a long-term commitment. For long-term workloads (like a year or more), Reserved Instances or Savings Plans would be more cost-effective. Spot Instances are better for interruptible, flexible workloads.
