A web application runs on Amazon EC2 instances behind an Application Load Balancer. The application allows users to create custom reports of historical weather data. Generating a report can take up to 5 minutes. These long-running requests use many of the available incoming connections, making the system unresponsive to other users.
How can a solutions architect make the system more responsive?

A. Use Amazon SQS with AWS Lambda to generate reports. B. Increase the idle timeout on the Application Load Balancer to 5 minutes. C. Update the client-side application code to increase its request timeout to 5 minutes. D. Publish the reports to Amazon S3 and use Amazon CloudFront for downloading to the user.
