I'm not sure, but I think A and D make sense because they call themselves within the function.

I agree with you, Novella. A and D seem to be recursive functions.

I'm not sure about option A, but I think option D is definitely a recursive function. It calculates factorial by calling itself with a smaller number.

I agree with you, Lindsay. Option A uses recursion to count down, and option D calculates factorial recursively.
