C is right Using Auto Scaling groups allows you to scale your backend services automatically based on demand, which can help improve performance during peak seasons. Using DynamoDB auto scaling provides a built-in way to scale the database dynamically, which can help improve read and write performance during periods of high traffic. This solution is highly scalable and efficient, as it allows AWS to manage the scaling and provisioning of resources automatically.
