I can give you a hint that the key is hidden among one of the options. And this is one of the times when custom choice is basically useless, as you don't have enough time left to check on both options. As I said, the key is somewhere in mentioned places, so coming up with a different place to search through would be pointless and get both of them killed for 100%.

So yeah, the choice is between A and B.
