Answer: By creating a new Lambda version and corresponding API Gateway stage for testing.
Option A is correct because it involves creating a new version of the Lambda function and a new stage on API Gateway for testing purposes. This approach allows other developers to test the updated Lambda function without impacting existing customers, thereby ensuring no service disruption. Creating a separate stage in API Gateway is a common and effective strategy for testing new changes in isolation with minimal operational overhead.
