Correct Answer: Option 1

Storing JSON in S3 and using AWS Lambda to process files offers a serverless, scalable, and low-maintenance approach. Lambda automatically scales to handle thousands of executions per day and integrates easily with S3 event triggers. Writing results to Amazon Aurora ensures high availability and performance on the database side, eliminating the need to manage servers.

Why the other options are incorrect:

Option 2: EC2 instances require provisioning and scaling, increasing operational overhead compared to Lambda.
Option 3: EBS Multi-Attach is limited in use cases and managing shared state across EC2s adds complexity.
Option 4: ECS with EC2 launch type still requires instance management. It's more complex than necessary for lightweight scripts.
