A Developer implemented a static website hosted in Amazon S3 that makes web service requests hosted in Amazon API Gateway and AWS Lambda. The site is showing an error that reads:
“No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘null’ is therefore not allowed access.”
What should the Developer do to resolve this issue?

A. Enable cross-origin resource sharing (CORS) on the S3 bucket.
B. Enable cross-origin resource sharing (CORS) for the method in API Gateway
C. Add the Access-Control-Request-Method header to the request
D. Add the Access-Control-Request-Headers header to the request
