Wait, is this a test on recursion or a stand-up comedy routine? I'm ready to bring the house down with some recursive jokes!

Hold up, is this a trick question? I feel like I'm about to get recursion-wrapped and thrown down a rabbit hole.

Hmm, B and C seem a bit off. I'm pretty sure they're not quite recursive enough. Time to put on my thinking cap!

Ooh, A and D look like they'll do the trick! I can almost smell the recursion working its magic.

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.
