I see where you're coming from, Lavelle, but I still think it's C) An object was expected but was not provided because the error is about the absence of an object.

Haha, classic JavaScript exception. I remember the first time I encountered this - I thought my code was possessed or something. But yeah, C is definitely the right answer here.
