(d) Three object gets referenced

The question was posed to me in a national level competition.

I want to ask this question from JavaScript and Memory Leak in portion Caching, Debugging and Animation of JavaScript

Answer 1

The correct option is (b) Two objects reference

To elaborate: Old versions of Internet Explorer could not detect cyclic references between DOM nodes and JavaScript code. A cycle happens when two objects reference each other in such a way that both objects retain each other.
