Suppose we add the following method to the LinkedList$)$ class.

def getfourthItem$($self$)$ Any:

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

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

$"1"."$

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

When would this method fail to satisfy its docstring?

The length of the linked list is less than $5.$

The length of the linked list is less than $4.$

It will always fail to satisfy its docstring since the method will return the node at index $4$ instead of the item.
