I will go with C I think to "allow the developer to perform a code push efficiently, without the need to update the API Gateway", this will require creating an alias referencing latest lambda version abd which can be referred to using API Gateway Stage Variable Reference https://aws.amazon.com/blogs/compute/using-api-gateway-stage-variables-to-manage-lambda-functions/

I will go with B It asks for push code to different branches, with stages you can define different branches such as DEV or PROD. The alias would just be a user-friendly way to address branches.

Yep, also for me is C. We can create different lambda versions, and assign an alias to the most recent and stable version. Then, in Amazon API Gateway we should refer at the ARN with functionName:alias

I say C, code branches are used to make a local copy of a repo for a dev to work on it on their local machine before merging changes back into the main branch - which may then be promoted to staging, QA, prod, etc as appropriate. Making an entirely new stage every time a dev pushes code makes no sense. Instead you would push the code into a new Lambda version and update the alias to point to it, with no changes on the API gateway.

Create 3 stages means you need 3 lambda functions. It is doesn't solve the requirement. It is C.

I think the answer is B. APi gateway stages allows you to map APi gateway to multiple Lambda functions. So at the API gateway side this is what we need to do. Using aliases at lambda function enables to use single lambda function with API gateway.
