Which option offers a discounted hourly rate compared to the hourly rate of On-Demand Instances?

Explanations:

AWS Graviton processors are a type of CPU architecture that can provide better price/performance but do not inherently offer discounted rates compared to On-Demand Instances. Discounts are provided through other pricing models.

Dedicated Hosts allow you to use your own licenses and provide physical servers for EC2 instances, but they do not offer a discounted hourly rate compared to On-Demand Instances. They are priced differently based on the host.

EC2 Instance Savings Plans offer significant savings (up to 72%) compared to On-Demand pricing for workloads that run continuously over a period of one or three years, making them ideal for long-term commitments.

Amazon EC2 Auto Scaling instances automatically adjust the number of instances in response to demand, but this feature does not provide a discounted hourly rate. Auto Scaling works with On-Demand, Reserved, and Savings Plans pricing but does not itself offer discounts.
