Answer: Utilizing API Gateway stage variables and Lambda aliases for environment-specific configurations.
The correct answer is A. Using API Gateway stage variables in combination with Lambda aliases allows developers to manage different environments efficiently without duplicating codebases. API Gateway stage variables can hold environment-specific configurations, and Lambda aliases can point to different versions of your Lambda functions appropriate to each environment. This setup ensures minimal overhead and eases updating and scaling across multiple environments. Options B and D are not optimal since they do not cater specifically to serverless applications, while option C involves unnecessary duplication of the codebase, increasing the management effort.
