If the variable 'x' is not defined, how can it be an object? I'm going with B, 'x-'.

I think the answer is C. 'undefined' 0. That seems to make the most sense based on the code.

I'm not sure about this one. The code looks a bit weird, maybe it's a trick question?

The output should be 'null' since the variable 'x' is not defined before it is used in line 02.

The code is trying to access a variable 'x' that has not been defined yet.
