Hi, I need a recursive function, not the one that iterates through the string and count the 'x' :)

What is the purpose of the base case in a recursive function?   A. The base case starts off the recursive process.   B. The base case defines the basis for the function calling itself.   C. The base case is what stops the recursive process.   D. All of the above are true.   E. None of the above are true.

Below, enter code to complete implementation of a recursive function palindrome() that determines whether an input string is a palindrome or not: 3. palindrome(s):
