5. (1 pt) The mystery method below belongs to a DLList data structure that implements the List interface using a doubly-linked list. 1 from Interfaces import List 2 3 4 class DLList (List): 5... 6 7 def mystery_method(self) -> object: & if self.n == 0: raise IndexError("List is empty.") 10 data = [ 11 for i in range(self.n): 12 data.append(self.get_node(i).x) 13 dummy.next = dummy 14 dummy.prev = dummy 15 self.n = 0 16 return data Which method name and description is most appropriate for the procedure defined above? Justify your choice. A. retrieve_data() - returns all data stored in the doubly-linked list B. clear() - empties the list of its contents and returns the data in a Python list C. copy() - creates a copy of all data stored in the doubly-linked list D. clone() - creates a copy of the DLList object and returns it. 5.
