A. B. C. D. Answer - D.
This is given in the AWS Documentation.
###########
When your API's resources receive requests from a domain other than the API's own domain, you must enable cross-origin resource sharing (CORS) for selected methods on the resource.
This amounts to having your API respond to the OPTIONS preflight request with at least the following CORS-required response headers:
Access-Control-Allow-Methods.
Access-Control-Allow-Headers.
Access-Control-Allow-Origin.
#############
Option A is invalid because you should not make the architecture change, since this is not the underlying issue.
Option B is invalid because this is the problem with CORS and not the stage itself.
Option C is invalid because using Cognito user pools would add one more unnecessary layer of authentication which is not part of the question requirement.
