Explanation:
Option B is the correct answer. Enabling a DynamoDB Stream on the table and configuring it to invoke an AWS Lambda function allows for near-real-time processing of document changes with minimal changes to the existing application code. This method efficiently captures item-level modifications and can automatically trigger the processing logic within the Lambda function, thus meeting the requirement for minimal code changes and prompt processing.
