Explanation

Amazon API Gatewayprovides a scalable and reusable solution for interacting with DynamoDB without requiring direct access by developers. By setting up a REST API with a POST methodthat integrates with DynamoDB's PutItemaction, developers can submit data (such as user ratings) to the DynamoDB table through API Gateway, without having to directly interact with the database. This solution is serverless and minimizes operational overhead. Option A: Using ALB with Lambda adds complexity and is less efficient for this use case. Option B: While using Lambda is possible, API Gateway provides a more scalable, reusable Option C: SQS with Lambda introduces unnecessary components for a simple put operation.
