So as a few of you guessed the answer to this one was multiple choice (F) or in letter form M. The pattern to this can be seen by looking down at your keyboard (the hint was supposed to be a key and a board, hard to draw a board haha). Looking at your keyboard you will see that the pattern looks like this:
So anyway user IWannaBeAnon mentioned I should change my comments section to moderated so that I can release all your guesses after I put up the solution, thereby not spoiling the answer for others. The winner this time is convictus who receives one point for the correct answer the fastest, and an additional point to icey for giving the logic for a second possible solution (even though it was not technically a multiple choice). Good job all and I can't wait to make the next puzzle! Also does anyone want to do a guest puzzle? I know I got no response last time I asked but figured I might as well try again.
