A developer is planning to use an Amazon API Gateway and AWS Lambda to provide a REST API. The developer will have three distinct environments to manage: development, test, and production.
How should the application be deployed while minimizing the number of resources to manage?

A. Create a separate API Gateway and separate Lambda function for each environment in the same Region.
B. Assign a Region for each environment and deploy API Gateway and Lambda to each Region.
C. Create one API Gateway with multiple stages with one Lambda function with multiple aliases.
D. Create one API Gateway and one Lambda function, and use a REST parameter to identify the environment.
