I'm going to go with `null` just because it's the most mysterious and least predictable option. JavaScript, you never cease to surprise me!

This question is like a game of hide-and-seek with JavaScript objects. I'm going with `undefined` just to keep things interesting.

I think the answer is `70`. Even though we deleted the `price` property from `customCar`, it still has the `price` property set to `70` from earlier.

Wait, didn't we just delete the `price` property from `customCar`? So, shouldn't the result be `undefined`?

I agree with Rasheeda, the value of result should be undefined.

Hmm, let's see. If we delete the `price` property from `customCar`, it should fall back to the `price` property of the object it's prototypically inheriting from, which is `car`. So, the result should be `100`.

I agree, it should be 100 since customCar falls back to the prototype's price property.
