On-Demand Instances allow you to pay for compute capacity on an hourly or per-second basis with no upfront commitment or long-term contract. You can launch instances whenever you need them and stop or terminate them when they are no longer required. There is no long-term commitment, and you only pay for the hours or seconds that the instances are running.

On-Demand Instances: On-Demand instances allow you to pay for compute capacity by the hour or second with no long-term commitment or upfront payment. You can run instances whenever you need them and stop them when you're done, with no interruption. This flexibility makes them suitable for applications that cannot tolerate any interruptions.

On-demand instances are a purchasing option for Amazon EC2 instances that allows users to pay for the instances they use on an hourly basis, with no long-term commitment or upfront payment required. On-demand instances are a cost-effective option because they are well-suited for workloads that are unpredictable or that do not require a long-term commitment, and they give you the flexibility to increase or decrease your usage as needed.

Selected Answer: A
A is correct. About Spot Instances Spot Instance interruption – Amazon EC2 terminates, stops, or hibernates your Spot Instance when Amazon EC2 needs the capacity back. Amazon EC2 provides a Spot Instance interruption notice, which gives the instance a two-minute warning before it is interrupted.
