Is this a bug in the quiz or am I doing something very wrong?

The question is ”fill in the missing code to add a clock event handler to all HTML button elements on a page:”

The code says this:

$(_).click(function() {


My answer was = $(’button’).click(function() {


What is wrong??

(1) ’button’
(2) 'button'
(3) "button"

I'm not sure what you used for quotes in (1) but (2) single quotes and (3) double quotes both passed. Note: (1) and (2) are not the same. It's easier to see with a larger font size.
