Suppose that it's the same as previous question (https://www.facebook.com/groups/mockamockingbird/permalink/146480429072398/) but I also add a fourth prize: D, this is also a fake prize. The conditions are the same: If you make a true statement, you'll get either prize A or prize B, if you make a false statement you'll get one of C or D.
For an unknown reason, you want prize C! Can you force me to give you prize C?
