Explanation
The correct solution to deploy a serverless application using Amazon API Gateway and AWS Lambda to development, test, and production environments with the least development effort is to use API Gateway stage variables and create Lambda aliases to reference environment-specific resources. This approach allows for efficient management and deployment across different environments without duplicating code or using additional services.Discussion
