Referring to the same method as the previous question, suppose we call this method on a linked list that fits the description in your answer.

What kind of error would be raised when we call the method, and why?

def getFourthItem$($self$)$ Any:

$""$ "Return the item stored at index $3.$

$($As with array$-$based lists, LinkedList indexing starts at $0.)$

return self.$\_$first.next.next.next.item

KeyError, because there is no "key" stored at index $3.$

AttributeError, because 'NoneType' object has no attribute...

TypeError, because the method returns a node instead of an item.

NameError, because the item at index $3$ is not defined.

IndexError, because there does not exist an item stored at index $3.$
