I have been asked this question by my college professor while I was bunking the class.

Question is from Mouse Events topic in section Document Object Model and Event Handling in Javascript of JavaScript

Answer 1

The correct choice is (c) onerror

Easy explanation: The onerror property of the Window object is something like an event handler, and it is triggered in response to JavaScript errors. It isn’t a true event handler, however, because it is invoked with different arguments.
