Scientists in a Certain Laboratory Are Working with a Linked

Multiple Choice

Scientists in a certain laboratory are working with a linked list class that uses recursion to compute its size.The scientists know that an empty list has size 0,so they never ask a linked list to compute its size when the list is empty.Under these circumstances,

A) the recursive method can become more efficient by eliminating the test for a base case
B) the recursive method should still handle the base case of an empty list,because it will still occur even though the scientists never ask for the size of an empty list
C) the recursive method can be modified to use a list of size 1 as the base case
D) B and C are both correct
