How are the Who Memed It? answer choices picked?

Just had a thought about this. For every meme the show puts up, the answer choices are always unclear -- that is to say, the correct answer is never obvious. So, how are the four answer choices picked?

My guess is that the producers take the meme and have other crew guess (from the list of everyone who submitted), and then the correct answer and top three crew answers are then put on the final presentation. It would make sense for why the cast always says each meme's choices "is hard."

What do you think?
