Fixing a CORS error

The app at https://app.example.com calls https://api.partner.com and the console shows "blocked by CORS policy: No Access-Control-Allow-Origin header". What is the correct fix?

A.Make the API send Access-Control-Allow-Origin: https://app.example.com, or call it through your own same-origin backend proxyB.Add mode: 'no-cors' to the fetch call so the browser skips the checkC.Add an Access-Control-Allow-Origin header to the request sent by the frontendD.Turn the request into a GET with the data in the query string
