In the previous example (http://pastebin.com/9xRk1CW1), why did we use andCallFake() to pass ajaxArgs in stubbing the AJAX call, rather than just using andReturn(ajaxArgs)?
A. We could have done it either way; it's just a matter of choice
B. $.ajax doesn't actually return the server reply content, so andReturn won't work
C. ajaxArgs is in the wrong scope, so its value is not "visible" to andReturn
D. We needed to be able to spy on (monitor) the AJAX call
