A developer writes the following code:
public with sharing class OrderController() public PaqeReference sendOrder() Order_c order = new Order_c insert order; ExternalOrder externalOrder = new
ExternalOrder(order);
Http h = new Http(); HttpRequest req = new HttpRequest(); req.setEndpoint(‘https://www.example.org/v1/orders’); req.setMethod(‘POST’); req.setBody
(JSON.serialize(externalOrder));
HttpResponse res = h.send(req); order = (ExternalOrder)JSON.deserialize(res.getBody(),ExternalOrder.class);
While testing the code, the developer receives the following error message:
System.CalloutException : You have uncommitted work pending
What should the developer do? (Choose two.)
A. Use the asyncSend() method of the HTTP class to send the request in async context
B. Ensure all callouts are completed prior to executing DML statements
C. Move the web service callout into an @future method
D. Use Database.insert (order, true) to immediately commit any database changes
