D)zero
E)None of these

The base case of the recursive factorial function is when the parameter is zero, as in the factorial of zero is one. If the function tries to calculate the factorial of a negative number, it will result in an infinite recursion. Therefore, the function should check for the base case of the parameter being zero before proceeding with the recursive call.
