I'm going to say "Z".
You 110% looked it up LMFAO and I know that for a fact because I just did
As long as I get it right 21 hours early.
So... you cheated? I mean, what's the purpose of putting up your answer that you searched up when the point of this is to test ones knowledge? The only thing you've proved is that you know how to type "what is Nazdaq's stock exchange letter?" in a search bar, and look at the first result because heaven and earth KNOWS you didn't know that less you are a stock/business approacher. I mean, I've taken a business class or two already, and I had no idea what the answer was. And do NOT even try to say you didn't because it's obvious you were trying to justify you searched it. Next time, if you can't think of the answer, don't oblige yourself to answer. I didn't answer for the one I DID know, yesterday. I don't want to sound unwelcoming, but I had to pour down into what needed to be filled, if you get what I'm saying. It was indeed cheating since you didn't know it, and decided to search it up. Whether it be textbook or search engine, you still had searched it up somewhere, somehow, somewhen. You really did NOT need to get it 21 hours early, so don't try to be a show-off. No one likes when others brag, purposefully or not.
I apologize Vip for putting something like this instead of an answer, so I'll just sandbag it and put "A"
