Wait, wait, wait... is this a trick question? I'm going with D) 'object'. Surely, the object representation of 'null' must be the output, right? *scratches head*

Haha, this question is a real brain-teaser! I bet the poor developer who wrote this code is kicking themselves right now. The answer is obviously C) 'undefined' 0.

I think the correct answer is C) 'undefined' 0. The code is attempting to concatenate the undefined value of 'x' with the string '0', resulting in the output 'undefined 0'.
