Haha, looks like the developer forgot to initialize the maxSpeed variable properly. That's a classic bug right there!

I agree with Olen. The debugger statement should allow us to inspect the state of the variables and the DOM element at that point in the code execution.

The correct answers are A) The values of the carSpeed and fourWheels variables, and C) The style, event listeners and other attributes applied to the carSpeed DOM element. I can see those being available in the console.
