Right answer is (a) Browser doesn’t release memory from objects unnecessary For explanation I would say: Memory leaks happen when your code needs to consume memory in your application, which should be released after a given task is complete but isn’t. Memory leak happens when the browser for some reason doesn’t release memory from objects which are not needed any more.
