As a truck enthusiast, I can tell you that the correct answer is definitely D. Anything else would be a load of rubbish!

Option D is the way to go. Why would we need to use `super.plate = plate` or `Vehicle.plate = plate`? That doesn't seem right.

Using super.plate = plate or Vehicle.plate = plate would not work in this case.

Hmm, this is a tricky one. I'm leaning towards option B, but I'm not 100% sure. I wonder if the instructor is trying to trick us.

I'm pretty sure it's option A. The `super()` call is used to invoke the constructor of the parent class.

Option D makes the most sense. We need to call the constructor of the parent class, which is Vehicle, and pass the plate parameter to it.

Yes, you're right. Using 'this.plate = plate' will set the plate property of the Truck class to the value passed in the constructor.
