Hmm, this one's got me stumped. I'll go with B) undefined, but I hope I'm wrong - that would be a real 'car-tastrophe'!

Clearly the answer is B) undefined. Deleting a property is like making it disappear - no more 'price' property means no more 'this.price' to return.

Yes, the value of result will be undefined after deleting the 'price' property.

I agree, deleting the 'price' property makes the result undefined.

Easy peasy, the answer is B) undefined. When you delete a property, it's gone, and 'this.price' will return nothing.

I agree with France, the value of result is undefined because customCar.price was deleted.

I'm going with D) 70. Even though the 'price' property is deleted, the 'customCar' object still inherits the 'price' property from the 'car' object, so 'getPrice' should return 70.

Definitely B) undefined. Deleting the 'price' property from the 'customCar' object means it will no longer have a local 'price' property, so 'this.price' will return undefined when called.

Hmm, this is tricky. I think the answer is B) undefined. The 'customCar' object inherits the 'getPrice' method from the 'car' object, but the 'price' property is deleted, so 'this.price' will return undefined.
